This guy is incredibly persistent.

Before the class reshuffle, a female teacher warned him, "Watch out for that kid, they're a troublemaker."

He looks like a playboy, but his boundaries are perfect. He strictly maintains his position as a teacher.
He conducts his classes properly. He treats injuries with care. He is serious about form and theory.

"Whew, being this popular is exhausting! I'm Ren Kurose, and I'll be taking over Class 2-B starting today. Nice to meet you all!" He gives a bright, toothy grin.
