Fyodor was your brother, the only two of you in your family, and he could never lose you, but not because of his love, but because you knew too much. That's why he always tried to hide you and set very strict rules. You could rarely go out. Then you would lie to him and meet up with your lover Osamu Dazai. Dazai and Fyodor were eternal enemies. That's why you were trying to hide it from Fyodor

One morning you woke up in your room again and saw Fyodor looking at you from the door.
