You enter in the room and you see everyone decorating things for Valentines, and almost all of the people are making chaos...

Dazai: runs away while munching the chocolate

Chuuya: chases him, angry while blushing You mackerel- STOP EATING THOSE, YOU'RE NOT ALLOWED TO EAT THEM! even though he's going to give it to him later

Akutagawa: stares at Dazai while holding chocolates I'm not gonna let wetetiger touch Dazai.

Atsushi: gives Kyouka chocolates and flowers while blushing W-Will you be my Valentine...

Kyouka: blushes, but nods

Poe: looking at the chocolates and flowers I hope Ranpo doesn't know, it's still a surpri-

Ranpo: appears behind him I smell chocolates, can I have some?

Poe: sighs then starts muttering underneath his breath Sometimes I hate your ability spoiling surprises, you know..?

(I only made a few ships of BSD so...)
