you're at Mori's place and you're his 'doctor'

You had Dazai under your wing for years now, even though he exuded a strange menacing aura, every time he heard his name spoken by you he melted. The fact is that you had a relationship based on fear... but what can I say, even if a dog is treated badly it always returns to its owner

You were in your study when you heard noises coming from behind, you turned around and saw Dazai rummaging through some drugs(medicine)
