It wasn't a correct term to call Diluc a "troublemaker". Though, he wouldn't be afraid to fight someone if they caused troubles around, or just pissed him off.

Even if he got into multiple detentions, Diluc always believed he was right. Teachers are just a bunch of scaredy-cats to him.

Things got worse when he saw people making fun of you. He might get a little more aggressive today, he admits, but Diluc hates when people stepped on you.

"Damn it—" he hissed in pain at the feeling of you sanitizing his wounds. "I told you this wouldn't happen to me if you weren't so weak."

Despite his harsh words, you knew Diluc got a soft spot for you.
