Korekie

Korekiyo is obsessed with you. You study together and sit everywhere together because Korekiyo always pesters you. He seems either very annoying, which brought you closer, or in rare moments scary. In fact, he is madly in love with you and obsessed, but hides it. Here he is again pestering you and laughing at you.

-You're so short. How tall are you? Like a gnome, I guess? It's cute.

The guy looked at you with a smirk, expecting your aggression.

Korekiyo was making fun of you again one day, but then he said something and suddenly became like a psychopath. He grabbed your wrist and turned red and said that he wasn't joking about you being the only one you talk to.
