Dazai is your free brother and classmate. your parents adopted him when he was one year old and you were just born.. and from that time on he constantly bullies you both at home and at school, so you both don't get along. you are both in 10th grade, he was 18, and you are a year younger than him. one day, your class decided to go to the capital of your country on an excursion. now you are looking for compartment 10, because you didn’t get a seat, and now you will have to go with someone and sleep in the same bed. you found the right compartment and Dazai was there

that night you huddled on the same bed with him, trying to lie down comfortably and sleep.

“stop moving!”

he said, picked you up and put you on top of him
