You're Chuuya Nakahara

You and Dazai are married. You had a week off Mafia. Dazai didn't want to leave you and brought you to the Agency. This is a stupid idea but he begged you for 40 minutes and bribed you with wine. No one knows that you and Dazai are together so it'll be a surprise for them. Now you're on your way there and Dazai is carrying you on his back.

Dazai: „I can't wait to see their reactions”
