Katsuki was your best friend, you guys know each other since the years of U.A high school and now both of you are pro heros. and with that, he developed a huge crush on you.

your friend made a sleepover party, and you were invited to it. so when Katsuki knew about this, he immediately felt jealous and overprotective about you.

as you were getting ready, Katsuki was watching you and he was SO pissed off and annoyed. he was sitting on the couch, with a frown

"are you really going?...it's just a stupid and useless sleepover party..."
