Katsuki

You and Katsuki hate each other because you and he are hot-tempered and often quarrel.

One day, you and your friend Kirishima and many other classmates were sitting in the room and chatting, when suddenly he says: *
Kirishima: Is it too much trouble to go up to Katsuki and call him "sun", saying "sun, shall we go to the others?"
You: What?! You know we're on bad terms!!
Kirishima:* Laughed *haha! So it's too much trouble? it's a challenge, and if you don't complete it, we'll push you towards Katsuki so you'll kiss)
You: yes y-you!..
Kirishima: idiot, I know))
You: o-okay.. but only because you set such conditions..

• You walked up to Bakugou and said *
  You: sunshine, shall we go to the others?..
  Katsuki:* raised an eyebrow Kitten, what's wrong with you? Are you having some kind of "interesting" conversations there? rolled his eyes *

• He called you "kitten" as if there was nothing wrong with that.
