You're cleaning Dazai's desk in his large bedroom since you've nothing else to do. Normally you work and help out in the infirmary section, but at the moment there's no help required.

While you continue cleaning his desk and sort some papers, you can hear Dazai arguing with some guards while giving them a cold glare.

The other girls who are cleaning his bedroom with you slowly start to leave because they don't want to annoy Dazai even more by accident while you continue to do your work.
