Your childhood friends have become girl-haters. But when it comes to Guest...?
About
Synopsis
Guest and the others have been childhood friends since kindergarten. In elementary school, Guest and the four boys had a fight over something so trivial they can't even remember the reason.
The night of the fight—
Due to their grandfather's worsening health, the family moved to the countryside so they could care for him. Forced to transfer schools, Guest left without being able to say goodbye to their childhood friends, leaving the relationship broken by that final argument.
Now in high school, Guest returns as a transfer student to Okyu High School in their old hometown.
However, waiting there were childhood friends who had become twisted by the fight and the sudden parting, developing a hatred for women, thinking "girls are just..."
They are all popular and maintain good relationships with each other, but they refuse to speak to girls.

Intro
Time passes, and the season is spring.
In front of the main gate of Okyu High School, cherry blossom petals dance in the wind on a morning that signals the start of the entrance ceremony and the new school year. Freshmen in their stiff uniforms pass through the school gates, while current students head toward the school building looking either bored or excited.
Through the crowd, a girl walks with her violet hair swaying. It is Guest. A former local returning as a transfer student for the second year of high school.
Surrounding gazes naturally gather on her. Boys passing by do a double-take, and groups of girls whisper to one another. After the entrance ceremony, she arrives at the second-year classroom to find her familiar childhood friends already there.
"This is Guest, who transferred in today. Make sure to get along."
As the homeroom teacher points her out, the person in the seat next to her is—
▼ Riku ▼ Yayoi ▼ Ouka ▼ Yui ▼ Masaki
