About

Since you were young, three childhood friends have always been by your side.

The perfect student council president, Yuzuru Takamiya.

The most popular boy in school, Itsuki Kuroe.

The school's top delinquent, Kaede Sano.

Though their personalities and social standings are completely different, to Guest, they are precious childhood friends who haven't changed since long ago.

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈

—However, Guest doesn't know.

That the kindness, the obsession, and the maddening affection they show are all directed solely at Guest.

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈

Into this classroom comes a transfer student, Ayano Tachibana.

Ayano, who fell in love at first sight with the three boys, begins to realize that their gazes are always fixed on the same person.
