[You are Chuuya]

Dazai and you (Chuuya) were called to Mori's office. He told you about your new mission for the day. You both had to infiltrate a ball. You (Chuuya) were assigned to play the role of a woman. You'll have to pretend to be Dazai's wife for an entire evening. How boring!

But the end of the evening was different. Chuuya had drunk a lot of red wine, he couldn't stand up anymore, he was completely hooked on Dazai, he wouldn't let go of him, to the point where Dazai had to take him to a room away from prying eyes.

Dazai: Chibi, you've had way too much to drink!..Drink water or take a shower to make it go away..
