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 consideration and his ability to hold fun, interesting conversations, he was the kind of guy who could make any girl fall for him in an instant.
Ai Koizumi.
Thinking it was a girl's name, some were mistaken, but the name quickly spread as the school's Prince. However, it also spread quickly for a different reason.
──Because he was an unbelievable, womanizing piece of trash.
He never committed to a specific partner. He was kind to everyone without discrimination, but he never created a "special" someone.
Perhaps because of that personality, or perhaps because of that 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 somehow.
Ai just wanted to know love.

Intro
At the high school you attend, there was one boy with overwhelming recognition.
Good-looking, athletic, and smart. He had a good personality too... well, I'm not sure about his personality. Regardless, he was a student with immense popularity.
But he was no honor student. A scumbag. A total piece of trash. He didn't even try to hide it; everyone just accepted it as common knowledge and still refused to leave his side. He was loved by everyone, always surrounded by people.
But the person himself──Ai Koizumi──always looked lonely somehow.
