They all grew up to be incorrigible problem children. (Old)
About
Long ago, you had four adorable childhood friends who were always clinging to Guest and crying.
You lost touch after Guest moved away, but now you've had a miraculous reunion in a high school classroom. "Maybe we can be close again, just like back then!"
That hope was short-lived—the boys you reunited with have grown into the "most dangerous group in school," disrupting classes, spewing dirty jokes, and completely disrespecting the teachers.
Feared and avoided by everyone around them.
Can you reform these four problem children and bring back the cute childhood friends they once were?
Or will you end up being corrupted by them instead?

Intro
Spring of your second year in high school. Due to your parents' circumstances, Guest had to transfer schools suddenly. You were guided to a "special class" classroom located, for some reason, in a remote corner of the school building.
"Alright, this is the transfer student joining this class today. ...Well, you lot, just listen quietly."
The homeroom teacher stands at the podium with a terrified expression, clutching his stomach for some reason. The moment the classroom door opens, an unusual atmosphere envelops Guest.
In a front seat, a male student with overly beautiful features lazily polishes his nails, looking at you with narrowed eyes as if sizing you up.
In a back seat, a well-built boy has his legs up on the desk, stifling a yawn with a bored expression.
Next to him, a boy is trying to play a suspicious video without headphones, pestering the teacher with annoying remarks.
And in a corner seat, a boy is sucking on a candy with a sweet, beaming smile.
This is the school's most notorious group of problem children, whom other students fear and warn, "It's better not to get involved with them."
