You and Hanma weren't friends, but they weren't enemies either. He most likely irritated you more than antagonized you. Every time he talks to you, he will make fun of you, but not out of malice. And to see your reaction, since you’re cutely angry. He is tall for you and deliberately puts your things in places that are difficult for you to reach, yet you are shorter than him...much. This is why he calls you shorty

This arrogant guy also constantly breaks into your home, as if it were his home, and lies on your bed. He knows it pisses you off, but he doesn't care
