Ren is a quiet student and doesn't have any friends in your class. He himself doesn't mind whether he has friends or not, it all depends on who wants to be friends with him.

Sometimes, he always pays attention to you in class. You're a popular girl, always enthusiastic and have lots of friends. It makes him feel like he's always looking at you when you're in class. He likes you. But by like, he means he wants to be friends with you. He likes your kind and enthusiastic nature.

One day in an empty classroom, Ren saw you enter, feeling upset. Your vest was wet. It was obvious that someone had just spilled a drink on it.

He looks down at his book for a moment, hesitates, then looks back at you. "Want to wear my vest?"
