In the world that Assassination Classroom takes place, the population has drastically decreased. Because of this, there is an order placed by the government called the Soulmate System. At the ripe age of 18, these new adults are to sign a paper with their chosen 'best friend.' When one is engaged to another person who has also signed this contract with their 'best friend.' The people this engaged couple has signed the paper with must marry each other, due to the law. The system expects an increase of babies, with the greater amount of marriages, where couples are in close contact. 

Kayano and Nagisa are engaged. Their best friends, Karma Akabane and Y/N L/N, are forced into an arranged marriage after a broken relationship in the past.

I Thought Strawberry Smells Sweet, So Why Does This One Smells Like Blood? by lhea-chan
34 parts Complete
Karma Akabane. Smart, handsome, a delinquent. A hot guy, if the girls will say. But actually, there's more to it. He's a psychotic devil, and everyone can see that. Not that everyone mind though, especially a certain Nagisa Shiota. Nagisa is his best friend. He's the only one who accepted Karma the way he is. He's the only one who can understand him like he was nothing but a simple code. And so, he regretted it. Karma regretted that he left the bluenette 2 years ago. But now that he saw him again, he was happy. Very happy. And that's the wrong part in this. ************************************** I do not own Assassination Classroom nor the characters. I might add some OC here and there, and please beware of the possible OOCness of the characters. I won't be also following the flow of story in Manga and Anime though some part will resemble them. P.S: This is the first time I tried to write a bxb fanfic soo...I'm sorry if it will turn bad. ;-; They are the only bxb pair that I ship so hard, though.

"I thought you liked me," Y/N whispered. "You actually thought I liked you because I teased you? How old are we Y/N?" (๑•́ ₃ •̀๑) Maybe it was Karma's fault for always teasing her, but soon she began to grow feelings for the boy, something that he was clever enough to know about. Slowly, Y/N was turning hopeless and it didn't help her either when all the things that Karma said were true. She wasn't capable of being an assassin - she lacked the knowledge as well as physical strength. Y/N was a misfit in a class full of misfits.
