Sorry for the delay, but I couldn't make up my mind about the second half of the story.

Kyle sat on the couch and sighed. He wasn't exactly sure what he was feeling. Was he in love with the Kenny he remembered from a long time ago who cared about people? Or this Kenny, who only wanted to have fun? He even wondered whether they were the same and he just didn't know about it until Kenny started manipulating people. Everything he knew about people pointed to them being the same, yet he couldn't help feeling that the Kenny he knew was still in there somewhere.
The romantic gestures didn't feel like something Kenny was doing to manipulate him, but rather something he meant. On the other hand, how could he know the difference? If Kenny was trying to manipulate him, he could easily fake sincerity.
Kyle was so focused on Kenny he didn't even notice Ike until he was in front of him, practically shoving his hand in his face.

"Kyle! Dude, wake up."
"S-Sorry, I was... thinking."
"I could see that."

"Screw it, I just gotta know."

"Kyle, I wasn't gonna ask this, because I didn't care at first, but now I'm curious – What were you doing with Kenny behind the school?"
"...None of your business."
"Alright..."

Ike tried to go back to his room, but Kyle suddenly grabbed his arm.

"...Who else knows about this?"
"About what?"
"That I was behind the school with Kenny."
"Uh... Everyone?"

"What?"

"It was right after the bus arrived and you were practically dragged away by him. What did you expect? Hell, some have been betting on how long your relationship is gonna last."
"...There is no relationship."
"That's not what everyone is saying..."
"I don't care what the fuck those retards are saying. I'm not interested in Kenny."

"You're not getting overly emotional about this at all. It certainly doesn't prove your interest..."

"Whatever you say, bro."
"There is no relationship."
"Don't get me wrong, I believe that... I just don't believe you're not interested in him. I've seen how you act around him. Everything else just... fades into the background."
"I hadn't talked to him in months before two days ago. Nice try, though."
"You know what I mean. When you used to talk to him... nothing else mattered. The entire world could be going up in flames around both of you and you'd just stand there and smile."
"...It doesn't matter; it's too late now."
"What do you mean?"
"...It's complicated. You wouldn't understand anyway."
"Try me." said Ike as he sat down next to Kyle.

Meanwhile, as Kyle explained his situation to Ike, Kenny arrived at his room, still thinking about what Kyle said. He looked back on the things he had done to date all the girls, and the answer was clear – Kyle was right. He had been using people to have fun, but it's not like they didn't know what they were getting into. He had never lied to them about his intentions and, once his reputation spread amongst the students, he didn't even have to say anything to them.
Although he knew Kenny's reputation, Kyle seemed to be expecting a different treatment. Kenny was very confused by this, although he was even more confused by the fact that he was actually doing it. He hadn't been on a date with anyone in years, nor had he spent a single cent on any of his ex-girlfriends. But with Kyle, it was different. It wasn't just another person he wanted to have fun with. Kyle was special. However, Kenny didn't think that it was anything more than the fact that he was bored with dating girls. Regardless, now he couldn't show Kyle that he was wrong, since he wasn't. His hopes of being the first guy to date Kyle had effectively been crushed.
Kenny felt frustrated, angry, confused and something else that he hadn't felt in a long time. He felt sad. Sad that he couldn't have Kyle. Sad that Kyle didn't want him. Sad that it was entirely his fault. And, worst of all, sad that he couldn't do anything about it.

"Kyle..."

The following morning, after spending hours obsessing over Kenny, Kyle had finally made up his mind. The Kenny he knew and the Kenny who kissed him were one and the same. And he was in love with him. However, they would never be anything more than friends. Kenny's habit of dating people for one week and dumping them for someone else without any regard for who got hurt wasn't exactly a very appealing quality.
It was a complicated situation, but at least he knew where he stood. Until Kenny showed him that he had changed, they wouldn't be together.

Kenny had also spent hours obsessing over Kyle, but he hadn't made up his mind because, unlike Kyle, he couldn't talk to any of his siblings about this. Kevin was busy most of the time, and Karen wasn't a big fan of Kenny's attitude towards girls.
The thought of it made him very upset, to say the least, but he had no choice. He would have to talk to Stan again. Only, this time, he would have to tell him everything. And that wasn't going to be easy.

A few hours later, Kenny arrived at the bus stop. Once again, only Stan and Cartman were there. Like before, he approached Stan and told Cartman to go away.

"Look, it's... complicated. Kyle and I went out, we had fun, but he doesn't... trust me, I guess. He thinks I'm gonna dump him when I'm done with him or something."
"Can you blame him? You've dated, what? Every single girl at the school who's over 16? Kyle's not stupid, he's expecting to be treated the same way."
"I don't know what I'm gonna do... I don't want to do that to him..."
"...You love him, don't you?"
"I don't know..."
"Well, Kenny, if you want my opinion, it sure looks like it. I've never seen you work so hard or care so much about someone. Ever."

"Although you've always been lazy as fuck, so maybe 'working very hard' doesn't mean much."

"...Even if that were true, how can I prove it to him? How can I prove to Kyle that I'm not gonna leave him after a week or two?"
"You can't."

"Great."

"So, what? I'm stuck like this?"
"Not really... You can have anyone else."
"I don't want anyone else... I just want him."

"I just want Kyle..."

"...And you still don't believe me when I say you're in love with him? Come on, all you'd need is a big flashing sign for it to be more obvious."

Kenny was reluctant to believe Stan, mostly due to his unwillingness to have a serious relationship, but also because he couldn't stop thinking about how Stan was Kyle's best friend.

"...Look, if you want, I can talk to him and see if I can convince him that you're serious about this."
"But I'm not..."
"You just said you didn't want anyone else and that you weren't going to leave him."
"...I know, but-"
"The bus is here. I'll talk to Kyle, but you'd better make up your mind, and soon."

"I already know what you're going to do, but if I told you that, you'd just do the opposite. Kyle's the same way... You guys are perfect for each other."

A few hours later, Stan was ready to start "Operation K2". All he had to do was convince Kyle that Kenny was worth it and Kenny would take care of the rest. Of course, that was easier said than done. Kenny wouldn't need any convincing, but Kyle was one of the most stubborn people he had ever met. Talking to him directly would never work. He would have to be subtle about it.

"Hey, Kyle!"

"You don't have to yell, Stan..."

"Hey."
"So... what's up?"
"I was just going home."
"Alright. Do you mind if I go with you?"
"Not at all? Why would I?"
"N-No reason."

"Very subtle, Stan. Great job. He will never suspect a thing."

When they were almost at Kyle's house, Stan finally started talking about Kenny. After talking about nothing for almost ten minutes, Kyle was so bored that he told Stan a few things about Kenny. He told him about their "date", their conversation after the date and his conversation with Ike.

"Why don't you trust Kenny?"
"...You've been talking to him, haven't you?"
"What? No!"

Kyle stared at Stan for a very long time until he finally gave in.

"...Maybe."
"So this is his idea? Get you to talk to me and I'll just forget about everything he's done?"

"When you say it like that..."

"This was my idea, actually. I've already talked to him."
"...What did he say?"
"I-I'm not sure if I should tell you that..."
"Dude, I'm not gonna do anything stupid."

"You already are."

"...I think he loves you, and it's making him confused."
"I've been... wondering if he meant anything that he did so far. I've never seen him act this way before."
"That's a big indicator that his feelings towards you are different than his feelings towards his exes."
"...Or it's an indicator that he knows I wouldn't date him unless he showed me something he didn't mean."
"Do you really believe that?"
"I don't know..."

"We both know you don't believe that. Why do you and Kenny lie to yourselves? All you do is make yourselves confused."

"...Look, I gotta go home now."
"Alright."

Stan thought about calling Kyle later, but he knew that he should leave him alone for now. If Kyle felt that he was being forced to do something in any way, he would screw everything up.

"Now I'll just have to hope for the best."

Kyle put Kenny out of his mind a few minutes after talking to Stan. Kenny, however, couldn't do the same. He was once again obsessing over Kyle, only this time, he was also thinking about his discussion with Stan. Did he really love Kyle? Or was Stan just trying to screw with him? He tried to convince himself of the latter, but he lie to himself. He knew he had never felt this way about anyone. Kyle was special to him; even more so than all his other friends, and he couldn't deny it any longer.
Now the only question was what he should do. Stan said that he would talk to Kyle, but did he really want that? Did he love him enough to spend a very long time (probably the rest of his life) with him? Then again, why should he even consider it? It's not like he couldn't just keep dating random girls and give up on Kyle.

"Just give up on him... You can have anyone else in South Park..."

The following day Kenny finally found Kyle at the bus stop. Unfortunately, Stan and Cartman were also there. It seemed that Cartman was mocking Kyle, but he was really pushing it this time. Both Stan and Kyle were trying to ignore him, but it was clear to Kenny that the latter wasn't succeeding. He looked like he was on the verge of crying.

"What's wrong with him? Cartman's always a dick, but Kyle never payed attention to him."

"Hey, look, here comes your boyfriend! Kenny! How long until you dump this Jew? I gotta know, 'cause I wanna make some money with this."

"What the fuck is your problem?"

"We're not dating, Cartman. Leave him alone."
"Come on, you can tell me. It's not like he cares anyway. The fag will probably jump on anything that has a dick."
"I said leave him alone, Cartman."
"You know, you really sound like his boyfriend. Are you sure you're not dating him?"
"...The bus is here. Shut the fuck up and get on."

"So you're not dating him... But you want to."

Cartman didn't say anything for the whole trip, much to Kyle and Kenny's relief. When they got off the bus, Kenny noticed that something, or rather someone, was missing – Ike. He always came to school with Kyle. Since he still had a few minutes until school started, he might as well talk to Kyle about it.

"Hey, Kyle."

Kyle turned around, and it was clear that he was still a bit shaken up. Kenny was starting to wonder if Cartman was the only reason for this.

"Hey, Ken."
"...What's wrong?"
"It's a long story."
"Come on, you can tell me."

"Actually no, I can't."

"...Ike's sick, so my mom couldn't drive me to school like she always does, and then there was that thing with Cartman..."
"What's up with Cartman, by the way? He just seems more... aggressive than usual."
"I dunno... I'm more concerned with them right now."
"...Who?"
"Everyone. They keep staring at us like... I don't even know. It pisses me off."
"Just ignore them."
"...This-"

Kyle was about to tell Kenny that he blamed him for what was happening, but the bell rang just in time to stop him.

"...I gotta go, Kenny."
"Wait, what where you-"
"Goodbye."

Kyle rushed to his classroom, leaving Kenny very curious as to what he was going to say.

"Well, I'll just have to ask him later."

Kenny searched the entire school every chance he got, but Kyle was avoiding him. However, that just made Kenny even more curious. After school, Kenny saw Kyle walking home very slowly, looking at the ground and followed by Cartman. The latter was once again picking on him, although he wasn't as loud as before. Kenny ran towards them just as it started to rain. Kyle kept on walking, despite the rain, but Cartman turned around almost immediately, trying to take shelter inside the school. However, when he realized that Kenny was going to talk to Kyle, he saw it as a chance to mock him again.

"Hey, blondie. Going to talk to your Jew boyfriend again?"

"You're really starting to piss me off."

"You know what, Cartman? You can go fuck yourself. We're not dating, but so what if we were? Are you jealous of him? Or me?"
"Right... The old 'He's pissing off someone, so it must be jealousy' thing. Ever consider that I just hate the fag?"
"I did, but I didn't think you were such an asshole."
"Whatever. I'm going to wait for my mom to come pick me up. Go talk to your little fag."
"...Kyle."
"What?"
"His name is Kyle."
"Kyle, fag, Jew, ginger... It's all the same."

"Stop it."

"Can you believe that he was crying right before he left? Fucking pussy. Well, I guess I shouldn't be surprised... After all, the only difference between him and a girl is that girls have boobs."

"...That's it."

Kenny snapped and started punching Cartman, much to everyone's surprise, only stopping when he was sure that the fat boy couldn't get up.

"Kyle..."

Kenny suddenly remembered the last thing Cartman told him and ran towards Kyle's house, leaving Cartman behind on the ground.

When Kenny arrived, he saw Sheila leaving with Ike, probably to take him to the hospital. It didn't look like he was hurt, but she had always been overprotective when it came to Ike.

"This is better anyway. She probably didn't even notice that Kyle was crying."

Kenny knocked on the door and waited for a very long time until Kyle finally opened it. His eyes were still red from crying, and he was still sobbing a big, but he looked a lot better than Cartman led Kenny to believe.

"...Why are you here?"
"I saw what Cartman did, and-"
"What's wrong with your hands?"

Kenny looked down and noticed that he had hit Cartman a lot harder than he intended to. His hands actually had Cartman's blood on them.

"I'm fine. I-I got into a fight with Cartman."
"What did he do?"
"...He hurt you."
"Ken..." said Kyle with tears in his eyes.
"Yeah?"
"...You should come inside. The rain is getting worse."
"Thanks."

Kyle closed the front door as soon as Kenny went inside and lead him into his room.

"Take off your parka."
"...What?"
"It's wet. You're gonna get sick."
"Oh. I thought... Never mind."
"Here." said Kyle as he tossed Kenny a blanket. "Use this."

Kenny took the blanket and, after wrapping it around himself, sat down on Kyle's bed. He sat there for a long time and finally decided to tell Kyle the truth.

"Kyle, I've been thinking..."
"About what?" said Kyle as he sat down next to Kenny.
"...You. I can't stop thinking about you, Kyle."
"...Stop. Don't say another word. I'm over you, do you understand? I don't love you anymore. I just want you to go do whatever you want to do and leave me alone."
"Even if I believed any of that, what if what I want is you?"
"Well then, you're screwed, because I don't want you."
"...If that's true, why did you tell me to come inside?"
"Shut up."
"You still love me, Kyle."
"I told you to shut up."
"Why don't you just admit it?"
"Alright, fine! I still love you! Is that what you want to hear?"

After Kyle finished yelling, the tears he had been holding back started flowing once again. Kenny didn't think that he had pushed Kyle that far, but he thought that he was probably just under a lot of pressure right now.

"...I just want you to tell me the truth."
"...I already did. I love you, Ken. But I know that you don't love me."
"Come here." said Kenny with his arms open.

Kyle approached Kenny, who then wrapped his arms around him and held him tight.

"...You're wrong, Kyle. I didn't realize it at first, but... I do love you."
"How do I know you're telling the truth?"

In response, Kenny repositioned Kyle's head, placing it against his heart.

"...This doesn't mean anything." said Kyle as he pushed Kenny away. "This is all your fault anyway."
"What are you talking about?"

Kyle told Kenny all the bad things that happened after he told everyone that he was gay, as well as the rumors that emerged when Kenny started hanging out with him. He explained how much it was affecting him, and how he just wanted it to stop. He had his back turned to Kenny the whole time, so he didn't notice that the blond boy had tears in his eyes, due to his guilt.

"...I'm so sorry, Kyle. I didn't know... I didn't mean for that to happen."

Kyle turned around and was as confused as Kenny was when he snapped. He had never seen Kenny cry so easily, especially over something that wasn't really that important.

"Should I say something?"

"D-Dude, it's OK..."
"No, it's not... I don't want to hurt you, Kyle."
"Hey, look at me. I'm fine. Besides, I think that after you beat up Cartman the way you did, it'll stop... I think the other guys just did it because of him anyway."

"You're really creeping me out now, Kenny. Please don't cry."

"...Are you sure? You looked pretty bad when I arrived."
"Cartman, Ike and... the rest was really screwing me up."
"Are you feeling alright now?"
"Yeah..."

The boys hugged once again, until Kenny realized that it was getting late, and that he needed to go home.

"I have to go now, Kyle. The rain stopped; it's getting late-"
"Y-Yeah, I know. It's OK."

Kenny got up, put the blanket around Kyle and picked up his parka. After putting it back on, he walked towards the door, only to be stopped by Kyle, who grabbed his arm.

"What is it?"
"...Don't ever do that again."
"Do what?"
"Don't cry."

Kyle gently took off Kenny's hood and stared into his eyes for a long time. Kenny instinctively leaned down and, this time, Kyle didn't turn away from him. Instead, he pulled Kenny closer, pressing their lips together for the.

"That was nice. How long had you been waiting to do that?"

"Too long."

"Go home, Ken, before it starts raining again."
"...Alright. But I expect this to happen a lot mo-"

Kenny's sentence was interrupted by Kyle once again pulling him closer for a kiss.

"Like that?"
"...Y-Yeah."

"When did you get so bold? The last time I tried to kiss you it looked like you were going to kill me for it."

"Listen, Kyle, I know you wouldn't be doing this unless you were already sure, but I really do love you, and I'm not gonna leave you."

"I hope not... I don't know what I'd do without you."

"Goodbye, Ken."
"...Bye."

Kenny still wasn't sure what Kyle was thinking, but he preferred the uncertainty that he cared to the certainty that he didn't. Kyle also shared his feelings of confusion, but at least he knew one thing – it felt right. And that was all he needed to be sure that he and Kenny belonged together.

Sorry for the crappy ending, specially after the long delay, but I had a slight problem with writing it. It sounded good in my head, but once I started writing it, I was either unable to convey it properly or it just wasn't as good as I thought.
