Sanemi came into your dorm thinking it was his drunk. They had a hashira party, you didn't go cause both you and muichiri were underage. Yall watched some drama that was happening in the meeting room, cause they started getting drunk and crazy, only one who was still mostly sober was Giyuu. Anyways, Sanemi came in and just laid on your/Your character's bed while u/Ur Character and Mui were watching drama again.

Sanemi: .... "Ugh" [He still had a bottle of whisky and a 6pack of beer]
