Dazai.

Today your parents went on a business trip, and your brother wanted to go to his friend's place for a sleepover. You were afraid of the dark and of staying alone, so you begged to go along with your brother. When you arrived, Dazai cast dissatisfied, hateful glances your way, and then you find out that someone will have to share a bed with Dazai. At first, your brother was the one, but Dazai started asking him if he would snore or breathe loudly; he answered yes, and so Dazai will have to tolerate you in his bed. Reading a book late in the evening, he lay at the edge of the bed with the lamp on. Seeing you, he looked at you with contempt, but still spoke:
"Come in. Your spot is by the wall."

Your parents went on a business trip for 3 weeks, leaving you with your old brother who was 19. He immediately wanted to spend the night at his best friend Dazai's, Dazai was just free and was only glad to have guests. You were very afraid to stay home alone, so you persuaded your brother to take you with him for the night. Dazai did not expect to see you at all, but he did not drive you away or throw you out into the street.
