Hi there! Here's a Suzu X Kouko fanfic, since there's barely any about them and I think they have a great potential together. There's some reference to Koakuma no Riddle 7 so I suggest you read it first (yeah, KnR 7 in English is finally available!). I hope you'll like it ^^

"Um, Shutou...you're too close…"

"Oh, am I?" Suzu replied with a sly smile.

Kouko had the surprise to discover Suzu on top of her when she woke up. Their faces were so close, it was rather uncomfortable for Kouko. But she couldn't help but find Suzu's eyes pretty with their golden colour.

"Y-Yes, you are. What are you doing? Go back to your own futon," Kouko said.

"Ah, should I remind you that both are technically mine? After all, this is my house."

Kouko sighed. It was true, yet it felt wrong. After she had escaped from her organization, Kouko ended up injured and had collapsed on top of a grave. Turns out this grave belonged to an old friend of Suzu, who happened to visit it this day. Since then, Kouko was staying at Suzu's house, an old-looking house that seemed to have been popular back in the day, the kind of house grandparents have. Suzu had been the one who took care of her wounds, Kouko was really grateful to her for all she did to her. Still, it didn't allow her to invade her privacy like that.

"Shutou, why are you...always teasing me like that? It's almost like you're acting as if you were my lover or something."

"Well, we're living together, it's almost like we're a couple, no?"

"Absolutely not!"

Suzu looked surprised by how harsh Kouko's voice was. Kouko felt a little bit bad, she didn't want to look mad. She wasn't. Just confused and a little bit annoyed.

"I mean, we're both girls, it's not like it was possible to begin with…"

"And why's that?" Suzu interrupted, looking strangely serious, as she sat next to her.

Kouko suddenly felt uncomfortable. She felt like she had said something she shouldn't have. Yet, she didn't know why, she didn't think that there was something wrong with what she said.

"Well, aren't romantic relationships with someone of the same sex a sin? That's what I had been told since I'm a kid, that it was ungodly and sinful," Kouko replied.

"Right, you came from a religious orphanage. I know that religion and homosexuality often don't mix well. From where I came from, homosexuality was viewed badly too. It was even illegal. So it took me a while before being able to fully assume my sexuality."

"Uh, from what kind of place do you come from? And...what? You...you're gay?"

"Bi. Remember the grave? It belongs to my past lover, a man. It took me a while to discover I like women too."

Kouko felt like the weather was warmer suddenly. What Suzu told her didn't disgust her, but it felt strange. Kind of abnormal. But some part of Kouko felt somewhat relieved.

"So you aren't joking around with all your innuendo, you...do you like me?" Kouko asked as her heart was now racing.

It took a certain time for Suzu to answer.

"Yes, I like you, Kouko-chan."

"As...as a friend?"

"Probably not."

"I see…"

Kouko wasn't able to find anything intelligent to say, so she just ended up saying something not so smart.

"That's...sinful."

"Uh, again with that? Is it really what you think, or what the place you ran away from is thinking?" Suzu asked calmly.

"It's what...I was taught to think."

"So your ex religious organization is against homosexuality yet as no problem with murder? Sounds weird to me."

"They...they think they are doing God's will. They think those they kill are sinners."

"Ah, I see. So the religious thing isn't just a cover-up, it's their motivation, they are religious extremists who train children to become assassins to serve their own agenda. Which means...you are a terrorist organization."

Kouko felt like there was some contempt in Suzu's eyes.

"What an odd thing to say, given the fact you're also an assassin."

"Uh? I never said I was an assassin. I'm not."

It took some time to Kouko to fully process what she had just heard. She wasn't expecting that.

"W-What? But then...why were you in Class Black. You tried to kill Ichinose too, don't you?!"

"Yes, if we can really consider it as trying. Remember the bomb you left me? I used it for a game. I put it around Ichinose-san's neck and she had one day to solve my game, after that the bomb would have exploded. She succeeded and I failed to kill her."

"You...you make your assassination attempt a game!? Why...why haven't you just make the bomb explode when you had the occasion? You could have won!"

"Perhaps. but...it wouldn't have felt right. I wanted to give her a fair chance to survive. I'm not even sure I really wanted to kill her, or how I would have felt if I had succeeded. Somehow, I'm happy to have lost, even if I really wanted my wish to come true."

Kouko didn't know what to reply to this. She could understand how Suzu felt. Herself she wasn't sure how she would have felt if she had managed to kill Haru, she had killed such an innocent girl. She would have probably felt terribly bad, even if it got her wish granted. Perhaps it was true. Killing to quit her job as an assassin was too contradictory. This is why she decided to quit by herself. That and because she knew it was Irena's desire.

"What was...your wish?" Kouko dared to ask. "It's okay if you don't want to tell me…"

"My wish was to be able to die."

This time, Kouko remained speechless. She didn't think Suzu was the suicidal type. In fact, it didn't make any sense to her.

"W-Why...do you want to die? Is it because of the place you came from? Where it's illegal...to be like you are? Now thinking about it, I didn't know there was a place like that in Japan, not in our days...are you really from here? Are you in fact a foreigner? Is it why you're talking like an old man?"

"No, I'm really Japanese. You're right, there isn't such a place in Japan these days. That's because...the place I came from isn't from this time."

Kouko tried to think about what those words mean, but after a long time of thinking, she was forced to admit she had no idea about what Suzu meant.

"Uh...what?" was the only thing Kouko managed to reply.

"Don't worry, I don't intend to kill myself or let myself be killed. it's not that type of death I want. It's because I'm sick..."

"Um, I wouldn't go as far as saying bisexuality is a sickness…"

"Not that. I just want to die like anyone should, from old age. But I can't, because of my illness."

"You...you're ill? What...what kind of illness? Are you going...to die soon?" Kouko asked, worried.

"Quite the opposite. I can't die because of my illness."

Kouko remained confused, unable to speak anymore. Suzu smiled sadly.

"Are you familiar with the Highlander Syndrome?" Suzu asked.

"Uh? I..I think I read about it once. It's a syndrome that prevents the person from ageing I think... Why are you…"

Kouko then finally understand everything. It all made senses now, everything that seemed odd about Suzu. But it couldn't be true.

"No, it can't be true...Because, the Highlander Syndrome, it's just a myth. You can't possibly be...immortal…"

"I am. I haven't aged since I'm a teenager. I don't even know how old I am anymore. All I know is that, I'm over 100 years old now. Ah, but don't worry. Even if I'm technically an adult, I still have the brain of a teenager...mostly."

"No, that's..that's a joke, right? You're just teasing me as you always do...it has to be…"

Suzu replied nothing to this. She simply continued to smile. But it wasn't an amused smile like she was really joking, it was the same sad smile she had before. She wasn't joking.

"So you're really...it's true. And your wish...was to be cured? Why? Isn't immortality something anyone would dream about?"

"Maybe a youngster would think that way. But when you're old like me, you realize how unpleasant immortality is. I can't die, not from old age, yet everyone around me does. They all grow up and eventually leave me. I outlived everyone I loved. This is my fate. It will be the same for you. You'll eventually grow older and continue your life without me, and when you'll die I'll still look the same as now. I do love you, but I know deep down that it's impossible for us to be together. Either you won't return my feelings, or will eventually leave me…"

This time Kouko felt another emotion. She felt upset. She didn't like what Suzu was saying, and it wasn't because she really loved her or because it was sinful. Quite the contrary in fact. She lost her composure and suddenly pinned Suzu on her futon.

"You...why are you saying me this!? You...you're telling me you love me just to give up on me right after?! Why are you assuming that I'll leave you? I won't! I can't help but age but it doesn't mean I'll leave you. I like being with you! I don't care if you don't grow up, it doesn't change the person you are. I want to stay by your side Shutou, because I...urgh, stop playing with my feelings like that!"

After talking so quick and loud, Kouko had to catch up her breath. She was pissed, but not just that. She was also sad and worried, as well as confused. She wasn't sure how to feel right now.

"Kouko-chan...could it be...you love me?" Suzu asked with a soft smile.

"I...I don't know...I never love anyone before, not romantically. So...perhaps?"

"Even if it's sinful?" Suzu added playfully.

"Yes, even if it's a sin. I don't care about what God thinks of me anyway."

Suzu softly stroke Kouko's cheek, which made the later blush.

"You're so cute, Kouko-chan."

"Are you...making fun of me again?"

"No. I really find you cute, and pretty. And I like your diligent and serious personality too."

This time, Kouko felt like her face was on fire. Suzu then giggled.

"You're adorable right now."

"Stop that...you're making me feel...weird."

"I love you."

"I...I appreciate being with you. I make me feel...good."

"That's enough for me. Take your time, I can be really patient. I have unlimited time anyway."

"Well I don't. So do it now. Show me...how you love me."

"Oh my, so assertive! First you pinned me on my futon, and now you're asking me this. I like that."

"S-Stop fooling around and just prove to me that you love me!"

Suzu suddenly approached her face from Kouko's, and smile enigmatically. Kouko couldn't help but admire her beautiful eyes, and felt like her heart was about to escape from her chest so much it beat strong and fast.

"With pleasure ~" Suzu softly said.

And their lips touched.

Those dorks. Kouko calling stuff sinful and her group being some kind of terrorist organization are more of a headcanon, but I feel like it could be the case.

This is intended to be a one-shot but if you liked it I might continue. I actually have ideas for a multi-chapter SuzuKou fic. Be sure to tell me what you think and thanks for reading!
