'

Dear Mori, I 'm about to do something stupid. '

Once again, Dazai was intimately grateful that his shitty doctor wasn 't at Hogwarts with him. He was 'certain 'Mori would hit him over the head and tell him to keep his head down 'follow the Slytherin prefects to the library until the troll threat was taken care of.

'

I mean, it 's not that stupid, '

he silently drafted the letter in his head, '

But you 'd probably still call me suicidal for it. '

Mori called him suicidal for most things. Like mixing random medicines together and speaking out of turn. Dazai slipped away from the group with all the care of someone who was used to getting in trouble whether they stayed in line or not.

Blaise watched him leave with a silent purse of his lips.

Then the letter would say, '

You told me to make a friend, but Blaise isn 't going to tell on me for running off. So this is kind of your fault, isn 't it, Doctor? '
