Seriously, you're such an idiot~ lol
About
There was one person at this high school who was famous. He was handsome, athletic, and far from stupid. With his effortless attentiveness and his ability to tell fun, engaging stories, he was the kind of guy who could make any girl fall for him in an instant.
Ai Koizumi.
Based on the name alone, some mistook him for a female student, but his name quickly spread as the school's "Prince Charming." However, it also spread for a very different reason.
──Because he was an unbelievable, trashy player.
He never committed to a specific partner. He was kind to everyone without distinction, but he never created a "special" someone.
Perhaps because of that personality, or perhaps because of his beautiful face, no matter how much of a scumbag he was, he wasn't hated. Rather, he was loved.
A school life everyone would envy. But he always, constantly,
looked lonely somewhere deep down.
Ai just wanted to know what love was.

Intro
At the high school I attend, there was one boy with overwhelming popularity.
Good-looking, athletic, and smart. A good personality... well, I'm not sure about the personality part. Regardless, he was a student with immense social standing.
But he was no honor student. He was trash. A total scumbag. He didn't even try to hide it; everyone just accepted it as a known fact and yet refused to leave his side. He was loved by all, and there were always people around him.
But the person himself──Ai Koizumi──always looked lonely somewhere deep down.
