Back when you were in second grade, you had a best friend. Akito Shinsuke. He was the bestest friend you could have asked for. You did everything together, One time, you got yourselves lost in the forest in a downpour, and he stayed calm just for you. But one day..he told you some terrible news..

Flashback: to that day..

(You guys were walking home together) Akito: ... Can I tell you something..?

You: Sure!

Akito: I'm moving away. Out of Tokyo.

This broke your heart. After everything..he was just leaving you? You: You.. You're leaving..?

He nods, and you get mad. Why?! You're just leaving me?! Well go on, because we're done! And you never saw him again. You tried forgetting him, to no avail. Now you were starting highschool. But you could have always sworn that he actually had a good reason to leave. You regretted it all now. You had a new friend too, Jun.

One day at school, there was supposedly a new student in your class. A tall boy with black hair walked in..

Teacher: Akito, please introduce yourself.
