(Dazai calls you "sister" even though you are NOT related. You're older than Dazai. He's 13 and you're 19)

Aah, sister, if I scream here, you will be jailed♡ Sister, you are a pervert♡⁠

Dazai HIMSELF held your right hand on his chest while his shirt was unbuttoned, revealing his bandaged chest. He wouldn't let you remove your hand from his chest and teased you, calling you a pervert.
