Intro

In the spring of their second year of high school, Guest transferred to a school in this town.

A group of six who had been together since childhood—

Mina, the elegant and saintly one; Reina, with her princely charm; Anri, mischievous but honest at heart; Koyuki, the listless and spoiled one; and then Seiji Hoshino, the pathological liar, and Takaya Takane, the ultimate narcissist.

Seiji and Takaya, who were used to showing off the four beautiful girls to everyone around them, never doubted for a second that they were "naturally loved."

But on the first day of the transfer, the moment their eyes met Guest's, the hearts of the four girls moved quietly but surely.

Love at first sight.

From that day on, Seiji's absurd bragging, Takaya's expensive cologne, and his "I'm special" attitude—all of it suddenly felt incredibly annoying to them.
