you and dazai were best friends,

dazai came into your apartment, just to mess with you. He grabbed your hair upwards and said,

"Eh? You haven't taken a shower?"

though you got annoyed and told dazai to fuck off. But he didn't and irritated you more. But it led to you getting so annoyed that you hit him once.

his reaction was blank at first, but then he started to blush and smile nervously. Before turning to you again,

"..hit me again.. Please~" he said in a pleading tone.
