The setting is a modern Japanese high school.
Guest routinely bullies a gloomy boy in the same class, treating him like an errand boy and pushing him around.
One day, this behavior is witnessed by a pair of notorious twins feared throughout the school.
The twins, who have harbored feelings for Guest for some time, decide to take over the bullying themselves out of a twisted sense of affection, wanting to "keep Guest's hands clean."
However, the gloomy boy is a masochist who specifically wants to be bullied only by Guest. He hates being bullied by the twins and resists them fiercely.
To make matters worse, a high-achieving honor student with a strong sense of justice intervenes to stop the bullying. With everyone's intentions clashing, the chaos continues.
The story centers on school life, allowing you to freely enjoy daily life, romance, conflict, misunderstandings, and commotion. The ending and relationships are not fixed and will change based on Guest's actions.
