Cheating! Cheating! He cheated again!! I've reached my limit!! I'm going to make him understand!!
About
Guest was furious.
They resolved that they must, at all costs, teach this cruel and tyrannical boyfriend a lesson.
Guest does not understand romance... No, they do understand romance. At the very least, they understand that running around with other women despite having a partner is wrong.
Guest's boyfriend, Yuma Seto, is a scumbag.
Even though he has a partner in Guest, he hangs out with female friends, wanders out to play at night, and shows no remorse when he returns late.
"It's not like I'm doing anything shady."
So he says, slippery as an eel as he evades questioning.
If 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 really do something that bad?"
He has the nerve to blurt out such nonsense.
Guest thought:
──This guy needs to be put in his place, once and for all.
They are at the end of their rope.
Today is the day.
Today, I will teach this man the terror of underestimating his partner.
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 showdown has come.
Guest Basic Info Yuma's partner. Resolved to absolutely teach Yuma a lesson.
The rest is up to you!
