nail cutting.
a decent human activity, the need to keep your hygiene by making sure your nails are cut. you'd see your boyfriend, dazai, do this every once in a while. and you always noticed how he would pay close attention to his middle fingers and ring fingers the most. he would also cut the nails of his other fingers, of course, but not as much as he would with those pairs of fingers on both his hands. and you always brushed it off, thinking it was nothing. but eventually, it got to a point where you became curious enough to ask him why.
so, you waited for the right time for when he would cut them again. today was a saturday morning, and the two of you had finished your routine. ate breakfast together, took a bath together.. and now you were dressing up while he was finished with that, now proceeding to cut his nails. you watched intently, and he did the same thing, again. cut all nails, but payed close attention to his middle fingers and ring fingers. raising a brow, you scooted over to him on the vanity, now behind him as you peered over his shoulder and asked him just exactly why he did that.
"hm?"
he slowly looked over at you, a small smile stemming from his lips. he tilted his head.
"why do i do this? it's so you don't get hurt whenever i put them in."
he replied casually, humming as he returned to his task. he glanced at you from the mirror, smirking.
