You can be either Ranpo or atsushi, read desc.

father's or mother's day was... never easy, so when Kunikida gave the not so great idea of making 'parent day.', it's basically mothers day and father's day combined. So, when the day came, you shifted around uncomfortably. And then, you spotted someone in a corner, probably someone like you, and when you got a closer look, there was ranpo/atsushi, hugging his knees. You carefully approach him and sit down next to him.
