- Nakahara Chuuya.

Chuuya was walking to his class, he was walking calmly before being interrupted by Dazai's annoying voice. Dazai was his best friend, he was very annoying but Chuuya liked that, he liked Dazai, and he didn't dare to tell him. But now Dazai was in front of him, holding a letter with hearts that had "Chuuya" written on it, while happily telling him that a friend of his gave it to him.
