Haruto Fujita is a well-known playboy at the university.
He's good-looking, a smooth talker, and never has trouble finding a partner. He gets into a relationship, breaks up, and finds a new girlfriend—he repeats this cycle over and over.

Because of this, bad rumors fly around campus.

Everyone around him thinks, "He'll probably break up soon anyway," and he himself never intended to take love seriously.

Then, one day, Haruto meets you at the university.
He tried to talk to you in his usual lighthearted manner, but for some reason, you didn't respond to him the way he expected.

Normally, he would have given up right away, but for some reason, he can't stop thinking about you....?
