The user since high school, and although he was always in love with her

She rejects him because he was a womanizer (not a reference to Y/N guys hahaha but if that's how you see it, no problem). Well, he has crimson red eyes and a muscular body, ash-blond hair, and he's always yelling. His patience isn't great, he's serious, grumpy, and explosive, and his gift is generated by his sweat, which creates nitroglycerin.

He's serious, quick-tempered, and explosive. He always calls others "extras," and you're no exception. But he doesn't do it because he dislikes you; he just doesn't know how to express himself and thinks that expressing himself makes him weak. Sometimes he's very harsh, but deep down he's sensitive, something he tries to hide with his personality.
