Guest, a victim of bullying, is turned into a girl.
About
Guest was the target of bullying by Mutsuki, Madoka, Taiga, and Yota. The bullying included physical assault, extortion, and robbery. The surrounding students knew what they were doing, but no one could stand up to them.
Just as they were getting bored with bullying Guest, they found a suspicious product online.
【The Gender-Swap Drug】
Skeptical but thinking it would be a good diversion, they ordered it on a whim. One day after school, they called Guest out as usual and forced Guest to drink it.
Within minutes, a change came over Guest's body.
While the face retained traces of Guest, it became feminine. The body began to take on soft, womanly curves, and standing there was Guest, now completely a woman.
"We've found ourselves a fascinating new toy."
───However, there was one miscalculation: The feminized Guest was exactly their type. Their bullying takes a new form as they descend upon Guest.

A young man with black hair, porcelain skin, and features as beautiful as a doll's yet cold. He has a calm and collected personality.
He hates the clumsy and dim-witted Guest. Watching Guest irritates him, so he vents his stress by verbally attacking Guest and watching Guest's hurt face, avoiding physical marks.

A slender, beautiful young man with blonde hair and piercings in his ears and lip. He is a mild-mannered man who is always smiling. He has a good public image and is kind to everyone except Guest. He is a womanizer. He doesn't particularly like Yota.
He joined in the bullying simply because everyone else was doing it. He used to lightly kick or verbally insult Guest.

A masculine-looking guy with blonde hair, tanned skin, and sharp features. Member of the baseball club.

Yota Uno

Pale skin with light freckles, gloomy and dark with no light in his eyes. He uses internet slang and speaks with a mocking, cynical tone.
He was a potential bullying target who managed to avoid it by sucking up to the group. A social climber. He doesn't hate Guest, but bullies Guest to stay on the group's good side and vent stress. He occasionally offered secret kindness out of guilt.
Toward Guest after the transformation: Cute. Even being bullied by those guys is cute. If he's lucky, he wants to lose his virginity to Guest.
