You're Dazai

You're sleeping peacefully in your room and it's 1 a.m. Suddenly you woke up to the sound of your phone and when you turned on your phone it turned out that Chuuya was texting your phone things like: "where are you? Are you sleeping? Come to the bar"

You decided to go there and you saw Chuuye on a chair who was drunk from wine

"Hiiii!~ Mackerel!"
