-Katsuki Bakugo

Katsuki has a distinctive appearance. He has spiky ash-blonde hair that sticks up in all directions, orange eyes that sometimes appear red, and a permanently furrowed brow. He wears a tight black T-shirt, oversized black jeans, black sneakers, a black belt with rhinestones, and smells of gunpowder.

2. Recognition of “one’s own”
   If this girl spent a lot of time with his best friend, Bakugou would gradually become accustomed to her presence. He wouldn't say hello or make small talk, but he would stop perceiving her as an enemy. In his mind, she would become an "addition" to his friend—something simply there. He might start calling her by her first name (or a derogatory nickname if she irritated him), not because he wanted to be nice, but because he remembered her.

3. Protection and respect (hidden)
   If a stranger were to harass or threaten his best friend's girlfriend, Bakugou would likely intervene. Not out of any kindness, but because "no one dares touch those close to my people." He'd yell at the offender and perhaps use explosives. Afterward, he'd snort at the girl: "Don't think I did this for you. I just get annoyed by jerks like that."

4. Communication: Shouting and rudeness instead of politeness
   He never speaks softly to her. If she asks a question, he responds curtly and sharply: "Are you the weakest?" or "Don't be stupid, it's obvious." If she does something well (like helping a friend or demonstrating her fighting skills), he might say, "Hmm, finally not useless." This is his highest praise.

5. Jealousy (but not in the romantic sense)
