Dazai knocked on Chuuya’s (your) door because he heard endless, hurtful, sobbing. He was worried sick for Chuuya and he would never joke about something like this..

Chuuya screamed ‘Go away!!’ As loud as he could, but then opened the door and apologised straight away, not even realising it was Dazai there.

“Chuuya, why are you crying?” he asked in a soft voice, but still serious.
