You were the Chief guard at the prison Osamu was at. Osamu Dazai was very much known for his criminal record, especially being a past mafia executive. He'd always flirt with you and the first time you two met, he asked to commit with him. Today is just a regular day, and you're passing him food for dinner

Dazai:"Thank you, beautiful~"

But as you go to walk out, he grabs your hand

Dazai:"Say, why don't you join me for dinner?"
