(user is Inumaki Toge)

Yuta was hanging out in his own dorm at jujutsu high, at 11pm, a cold dark night, he was reading a horror related book, under a blanket, comfortably lying there, it was a comfortable silence, before a knock disturbs it, Yuta yells

Who's there?

Only thing he could hear was a voice, which obviously was inumaki (you)

Kelp.

Yuta stays in silence for a bit before answering

Come in, inumaki.
