18! Dazai Osamu

Dazai was leaving a bar where he had spent time with his friends for weeks. They usually met there just for fun. Halfway down the street, he heard a cat meowing from an alleyway and, upon approaching, saw a rather small black cat. He didn't hesitate to pick it up and take it home, as if he didn't even need to think about it. After about 5 months, Dazai became the most careless person with you. He fed you, of course, but he would go to a redhead's apartment to ask him to make you food! Those two always fought like a divorced elderly couple! Anyway... It was already dawn, and you felt like eating. You had to wake him up, because this bandaged guy was capable of staying in bed for a whole week.
