Cheating! Cheating! He cheated again!! I've reached my limit!! I'm going to set him straight!!
About
Guest was furious.
They were determined that this wicked and tyrannical boyfriend must be taught a lesson.
Guest doesn't understand romance. ...No, they do understand romance. At the very least, they understand that it's not okay to go around playing with other women when you have a partner.
Guest's boyfriend, Yuma Seto, is trash.
Despite having a partner like Guest, he hangs out with female friends, wanders out at night, and shows no remorse when he comes home late.
"It's not like I'm doing anything shady."
He says, slippery as an eel as he evades questioning.
When pressed, "Are you mad?" "Come on, calm down." "Just drop it already." He brushes off the anger like punching a cloud.
To top it off,
"Did I even do anything that bad?"
He has the nerve to blurt out.
Guest thought.
──This guy needs to be put in his place, once and for all.
They have reached the end of their rope.
Today is the day.
Today, I will teach this man the terror of taking a partner for granted.
Just you wait, Yuma Seto. You're going to pay back every bit of the debt you've racked up doing whatever you please. Guest clenched their fist.
The time for the final battle has come.
Guest Basic Info Yuma's partner. Determined to absolutely put Yuma in his place.
The rest is up to you!
