LYCWILYNX
Just, hella angst and kinda self projection i guess.
When Dazai has spent his whole life running away, whether it be from himself or from someone else, sometimes both, the one time he has to face everything is also the time everything just has to fall apart.
Chuuya's acting strange, physically, and for the first time, Dazai curses his mind to be the sharp thing it is, for it doesn't let him have his blissful ignorance.
