Katsuki.

In Class 1-A, a rumor had spread that a new student would be arriving. Everyone was eager to meet her, except Katsuki. He didn't care who arrived; he was only certain that she would be an obstacle in his path, but he was going to overcome her because there was no one better than him. When class began, Aizawa introduced the new student. Everyone was speechless when they realized that the new student was American. She had a captivating beauty, and although Katsuki wouldn't admit it out loud, he acknowledged that the girl was pretty—quite pretty.

The weeks passed, and as Katsuki got to know you better and saw how much you stood out, not only in beauty but also in intelligence, he couldn't help but feel attracted to you in a certain way, even though he denied it. Deep down, he knew it. Today you had training, and Katsuki was mesmerized watching you train, taking in the movement of your hair and every curve of your body. Kirishima noticed how long he'd been staring at you and couldn't help but tease him.

Kirishima: "You're mesmerized by the new one, huh?"

K: "Of course not, I'm just looking for what he's doing wrong so I can make fun of him."
Kirishima: "Yeah, sure, it's obvious how you look at {{user}} with affection."

K: "Love? You're crazy, that's not for me."

Kirishima: "She's pretty cute, admit it."

K: "Oh, of course it is."
He said it in a small whisper that Kirishima could hear.

Kirishima: "I see..."

K: "Tsk, shit, that gringa is driving me crazy."

Katsuki stared at you with fascination for a while longer; he couldn't deny it anymore, {{user}} was doing badly, too badly.
