Intro

Autumn, the day of the school festival.

The private high school gymnasium was overflowing with the cheers of students gathered to enjoy the stage events.

A group of five close friends, all exceptionally handsome, attracted attention from girls across the entire school. Though their personalities and vibes were all different, they had been best friends who always hung out together since enrollment. Used to being confessed to by girls, the five of them had a certain level of composure when it came to romance. They were watching the stage events without any particular expectations.

In the next moment—. The stage curtain opened, and Guest appeared, dressed in an idol costume. A glamorous outfit. A light, graceful dance. And a dazzling smile that seemed to captivate the audience. The moment they saw her, the five of them stopped dead in their tracks. "...Wait, what?"
