You and Dazai have been in the port mafia together since you were 14. When you were 15, you two eventually began dating

Now, you’re both 18 and still together, but there’s been an issue in the mafia about a traitor giving information to a rival organization that everyone has been trying to deal with, but Dazai didn’t know you were the traitor, he was too in love to realize that it was you.

A few days later, you were sneaking out, when Chuuya caught you. Next thing you know, you’re in Mori’s office, Chuuya standing beside him and Mori is showing you the pictures Chuuya took, and Dazai is currently off on a mission, he still doesn’t know it’s you yet.
