Notes:

Hi, I'm back with another KaiShin! But it's a KIDCon this time :3

WARNING: This is written for me to expend some KIDCon feels, so if you're not comfortable with KIDCon, you might want to sit this one out because it has T-rated scenes.

Sorry for grammatical and spelling errors! (Also the kinda lame title…I don't know what to use anymore, unless you have a nice suggestion that would fit this story better. That'd be appreciated! Thank you very much!)

PREMISE: KID doesn't know that Conan is Shinichi, and Conan is 9 years old

I hope you enjoy!

The night had started like any other heist night. Kaitou KID had appeared and had stolen the gem with a mocking laugh; the taskforce had given chase and got trapped in some ridiculous trick involving glue, glitters and feathers; KID had released a dummy which Nakamori-keibu had fell for again; and he'd followed the notorious phantom thief to the real escape route, which was in the 30th floor of a new hotel that decided to host an art and jewel exhibition for their opening to lure in people and prospective customers.

They were in one of the rooms that had a balcony facing the back view of the hotel, and Conan knew that KID wanted to jump off from there. It was a perfect spot, after all, since there was a vast forest beyond and there were no people in that area. Following on foot would have been hard, and the inspector was denied the use of helicopters or anything that can distract the guests by the hotel owner.

They had a small showdown in the spacious and well-decorated room, which was only illuminated by the soft and dim glow of the moonlight; card shots were fired and soccer balls were launched. Surprisingly, there was minimal damage except for one fallen painting, plus indented cards and deflated balls on the floor.

They had been exchanging banters and jumping all over the place. Eventually, Conan had hopped on the bed to dodge a razor-sharp card, and KID followed to close in further and taunt him.

Everything had been normal−at least when it came to a Kaitou KID heist−up to that point.

The deviation from their usual cat and mouse routine started after Conan had tripped the thief by pulling the sheet. KID, however, twisted to avoid getting his face bashed on the floor and instead momentarily slipped on the silky bedding and fell down on the shrunken detective with a grunt.

Both of them had been fairly surprised and too shocked to move. Kaitou KID, the ever graceful enigma, had slipped. Conan had blinked and stared up at the shadows that hid the thief's features, then let out an amused snicker, which evolved into a full-blown laughter. KID had grumbled, if only for a moment, before he had grown silent and watched the bespectacled child take off his glasses to wipe a tear at the corner of his eye.

This wasn't really expected, not to him, and not even to the phantom thief, he deduced; and that's saying something. They were always relying on the quote Expect the Unexpected, after all.

"KID?" he called out, seeing as the person above him grew silent. Conan gave the other a small frown before attempting to sit up and put his glasses back on his face; but that was all it had been: an attempt. Out of the blue, KID pushed him back on the bed and took his glasses away from his hand. Conan made a confused noise and then tried to grab the glasses back, but KID raised it out of his reach and let it disappear with a small puff of lavender smoke.

"What are you−" He started, but was cut off when the thief leaned in closer. Too close. The faux child could feel the other's warm breath on his lips that sent blood rushing to his cheeks and ears. "…KID?" he murmured softly, trying to ignore how his heartbeat seemed to accelerate. "Are you okay?"

He almost jolted when he felt something warm on his cheek. His eyes widened in incredulity; KID kissed him. On the cheek. Conan gulped and tried to stomp down on the nervous anticipation that suddenly decided to make itself present in his chest, only to fail when KID whispered in his ear with a low voice and a hot puff of air.

"I'm fine, tantei-kun."

Conan turned his face away from KID, trying to hide the fierce blush that crept up to his cheeks, not even trying to wonder if the other can actually see his face in the dark room. "Won't you get up already?"

"Not yet," KID said. Conan frowned again and was about to shoot off a retort, but his expression eased into confusion when KID reached to cup his face with a gloved hand. KID leaned in again, and the detective's lips pursed in tension. He tried hard to ignore the fact that his heart was acting like a wild animal pounding on its cage, waiting to be freed.

"Seriously, what are you doing?"

"Shh," was all KID murmured, before his lips pressed onto Conan's gently.

His eyes widened. Eh? EH?!

The kiss lingered for a couple more seconds before KID pulled away slowly. Conan wanted to protest, but whether it was about pulling away or the fact that KID kissed him at all, he wasn't really sure.

They were silent for a while; whether it had been seconds or minutes, Conan didn't know. He opened his mouth to say something, but his voice was caught in his throat. KID's gloved hand that was still resting on the detective's cheek moved to tilt the chin. Conan saw the thief leaning in again, and unconsciously, his eyes fluttered shut.

There it was again. The soft press of KID's lips on his and the roaming hands leaving mild touches on his person made him quiver. The thief deepened the kiss for a short moment before pulling away again to trail kisses on his jaw.

Conan bit his lip as he tried to hold back the moan that threatened to escape him. A gloved hand ran down his side gently, as the other one caressed his cheek. The faux-child shifted slightly from his position on the bed and, to his mortification, let out a loud gasp when he felt something wet and warm on his neck. "K-KID," Conan mumbled weakly, his face flushing further when the thief made suckling kisses. He reached up to grasp at the lapel of KID's white suit jacket as he fidgeted from his companion's administered touches.

KID pulled away and smirked at Conan's red face. "You look absolutely lovely, tantei-kun," he purred lowly, and the not-child fought down a shiver.

"Why…why are you doing this?" Conan panted out as he let go of KID's jacket. The thief looked away for a second; the new angle of the previously silhouetted face, plus the moonlight's faint glow, allowed Conan to see a hint of pink blush on the other's visage. Looking back at the detective, KID smiled. "I don't really know," he admitted, and Conan let out a growl.

"Bastard," he snarled, attempting to shove KID away, but to no avail.

The thief shook his head apologetically. "I'm sorry, I meant that I don't know what possessed me to do this." KID gave him a light kiss. "I'm a thief. And you're a detective−nothing but a critic to artists. But you proved me wrong, Tantei-kun. You're more than a critic. Much more than that."

"I don't understand," Conan said. "I'm nothing special. I'm a plain detective like all of your detectives."

KID chuckled. "That's not true. There's a reason why you're my favorite."

He furrowed his brows. "And what is that?"

"Well, for starters, you're the one who's come the closest to catching me. Nakamori-keibu is learning, but still not quite there yet. Hakuba is pretty good, but I find his strictness a bit boring. Plus, he annoys me. That guy is somewhat of a stuck-up prat most of the time."

Conan laughed at that. It was true; Hakuba does seem uptight, especially when it came to KID. "You're a critic to critics. So, what about me? What do you dislike about me, Kaitou KID-san?"

KID snickered. "Hellish soccer balls," he answered automatically, making the not-child snort.

"Figures."

"But it's something that I like about you, too," KID muttered. "Tantei-kun, you're exceptionally intelligent. A genius. You're a quick-thinker and you keep me on my feet. You're willing to bend the rules to get to that one truth that you always seek. You're amazing."

Conan's face colored. "KID, I−"

"But recently, I realized something. I feel like I can trust you. I feel like I want to get close to you even though our meetings are limited. I feel like you'll be able to understand me far better than anyone would be able to. There's just…something about you that I can't explain," KID said as he brushed the faux-child's cheek with his thumb.

Conan let out a soft exhale. "KID…"

"I love you."

Conan felt his breath hitch. "W-what?" he stammered, his question perfectly reflecting the one in his head.

"I love you. That's what I realized." KID was nothing but serious, Conan noted. He felt a hard tug at his chest. If felt rather painful, but not entirely unpleasant. He gulped nervously.

"But I'm just−"

"I know. You're a nine year-old kid. The thing is, I don't know why I acted on my feelings tonight," KID whispered. "Sorry. You must feel really weird. I understand that it might be wrong, but it's not like I'm a complete pedophile. I got attracted to your intelligence and potential first. The urge to kiss came after."

"I…" Conan trailed off, and licked his lips. KID watched the action carefully, and the small detective felt something twist in his stomach.

"Tell me, Conan," KID started, and he suddenly felt bitter about the thief's use of his fake name. He wanted to hear KID call him with his real name. The thief ran his gloved fingers through Conan's hair.

"I know that this whole situation seems insane, but…do I have a chance?" KID asked, looking solemn and silently hopeful.

Yes. Yes, you do.

Conan felt heat rise to his cheeks and stubbornly ignored his previous thought. "I…don't even know your face and your real name…" he mumbled, and KID chuckled.

"I can fix that." The thief reached up to pull off his top hat, but Conan quickly grabbed at his arm. "Wait!" he exclaimed, and KID gave him a curious look. "Wait. Are you really sure you want me to know? I can…I can turn you in. Why do you want to risk it?"

KID's lips turned up. "They say that love can make you do crazy things. I'm sure, tantei-kun. I trust you."

Conan felt something warm spread in his chest at the thief's words. His heartbeat quickened, and he reached up to place his hand on KID's cheek. The thief instantly leaned in to the touch, and Conan let out a shaky breath. "…okay."

Conan pulled his hand away, and KID took off his top hat to show his messy brown locks. The thief took one of Conan's hands and placed it on his monocle. "Remove it," he said, and the faux-child nodded hesitantly and pulled off the accessory. Clutching the monocle to his chest, Conan stared at KID's bare face for the first time, and was surprised to see the thief's similarity to his older self. The cheek he touched earlier was warm, confirming that it wasn't a disguise. The more he stared, however, the more apparent their differences became.

Another quivery breath passed through his mouth as he took in the other's eyes; they were indigo and beautiful and sparkling with life, and Conan found himself sitting up slightly to look at KID's face closer. Dropping the monocle beside him, he cupped KID's cheeks with his tiny hands, and felt butterflies raging in his stomach when KID's eyelids lowered, long lashes brushing against his cheek lightly. Leaning in further to let their foreheads and noses touch, Conan turned redder as he felt the thief's hot breath on his lips.

"You're beautiful," Conan murmured, and KID shut his eyes and closed the gap between them, and the two fell back on the bed with a soft thud. The thief deepened the kiss, and Conan entangled his fingers in the other's hair. After a few more moments, KID broke the kiss and smiled. "I'm Kuroba Kaito, magician extraordinaire. Call me Kaito," he said.

"Kaito," Conan murmured, testing out the name, and saw KID's eyes glimmer.

"I love you, Cona−"

The faux-child quickly cut him off. "No. Don't call me that. My name is not Conan."

Seeing the confused expression on the thief's face, he sighed and gave the other a small grin. "Do you remember the Clock Tower heist?"

Blinking, KID nodded and let out a soft hum. "Yeah. That had been a close call. The person they call as the Heisei Holmes was there, in a helicopter. He was a challenge, but sadly he never attended my other heists." Looking at Conan's unwavering smile, KID frowned in thought, before his eyes widened. "Wait, don't tell me…you're that guy?!"

Conan chuckled. "That's right. My name is Kudou Shinichi."

KID sent him a curious look. "But how? I thought Kudou Shinichi is a high school detective."

"He is. I am." Conan let out a bitter laugh. "When I was 16, I got poisoned by an untraceable drug that was supposed to kill me. I guess I'm lucky enough that I survived. Although, it did turn me into…this."

KID's lips pursed together. "Poisoned…" He gave Conan a worried look as he stroked the detective's locks again. "I'm glad you survived," the thief murmured into the other's hair.

Conan smiled. "Thank you." Gently, he pushed KID away far enough to see his face. "Hey," he started, and KID perked up.

"Yes?"

He placed his hand on the thief's face again and stroked the cheek with his thumb. KID's skin was soft and warm. Conan gave him a half-lidded gaze, his cerulean eyes glimmering from the cluster of emotion that suddenly bloomed in his chest.

"I've always thought that I'd be with Ran. But…she moved on, because I've been gone for far too long. It hurt, at first. So, I focused on being a child. Became the little brother she wanted me to be. Distracted myself with case after case. Went to all of your recent heists."

"I've noticed," KID commented quietly with a nod.

"Yeah. Your heists are really great. They're fun, and you're wonderful." Conan chuckled when he saw KID's cheeks and ears turn pink. "But you know what I enjoyed the most? It's the fact that you treat me like an equal and clash wits with me without holding back, even though I look like this. I feel like I'm myself, even though you didn't know my true identity. Thank you."

KID gave him a smile. "You're my greatest rival, I really didn't care if you're a kid. But," he paused, taking one of Conan's hand and placing a kiss on it. "I'm a little relieved to hear that you're actually older. I didn't really want to think about how much I wanted you even though you're supposed to be a nine year-old brat."

Conan blushed. KID wanted him. He breathed heavily. "Kaito," he mumbled, tugging on the thief's suit jacket to bring him closer. Staring at those shining indigo eyes, Conan tightened his hold on the lapel. "Kaito," he repeated, his voice raw with emotion, and he saw KID's eyes widen a fraction. "I love you too."

"Shinichi," KID breathed out, his eyes glimmering further, and Conan let out a whimper. That felt good. Being called by his name felt good, and KID seemed to notice. Conan closed his eyes, and KID complied with the silent request. Leaning in, the thief pressed their lips together. Conan entangled his hands in KID's soft brown locks again and tilted his head slightly to deepen their kiss. He felt a warm hand on his face, and another combing through his hair. KID had taken off his gloves, Conan thought passively. He didn't notice when, though. KID's warmth kept him too occupied.

Something wet prodded at his lips gently, and Conan opened his mouth willingly. He let out a soft moan as KID's tongue curled on his. Conan responded and sucked on the wet muscle, making KID whimper shakily. They kissed for another minute or two, before they pulled away.

Conan noticed that KID's eyes were moist. "Are you crying?" he asked.

KID grinned and shifted off of Conan. They lay on the bed facing each other, and KID pulled his detective closer. The thief pressed his face on Conan's chest and wrapped his arms around the tiny waist.

"Hm, maybe? I'm just happy," KID replied, sounding meek and relieved. Conan's face softened and he caressed KID's hair again.

"I'm happy too," Conan said, but choked on the last word. He felt relief as well; the thought of having someone by his side who he could completely open up to was too overwhelming that he also had tears pricking at the corner of his eyes. He knew that KID felt the same way. "Stupid thief," he murmured. "Your tears are somehow contagious."

He heard KID make a muffled and lighthearted laugh. The thief looked up at Conan's cerulean orbs. "Are we dating?"

A blush bloomed on Conan's face. "Oh, um. Yeah, I guess…if you're really fine with me being like this."

KID smiled. "Of course I am."

"Are you sure? I…there's some chance that I won't find a true antidote…"

"I'm sure, Shinichi. It doesn't matter if you find a cure or not."

"Kaito…"

When the two finally decided to flee from the heist location at two thirty in the morning−but not before KID made sure to not leave any incriminating evidence that might lead to Kaito or Shinichi−they talked with hushed voices about the details of both of their cases on their way home. KID explained Pandora and Snake's organization, and Conan revealed the details about his shrinking and the people behind it.

Thinking that there might be some connection to the two organizations, they agreed to set a time for a thorough discussion.

By the time they reached the Mouri Detective Agency, it was already quarter to four in the morning.

"This is my stop," Conan said. KID, who was disguised in dark clothing and a black cap on his head, nodded and gave the not-child a quick peck on the lips when he was sure that no one else was around to see.

"I'll see you this weekend," the thief whispered. "And try not to let the Mouris catch you going back to bed. You snuck out for the heist, after all, you sly detective."

"I'll try." Conan grinned. "See you soon."

Notes:

I tried to have some emotional KIDCon…maybe? I'm not sure if I succeeded in making this feel like it had a lot of emotion.

If you have time, a feedback would be nice! :3

More KaiShin soon! And I started my multi-chaptered story, yay!

Thank you so much for reading!
