Love or revenge—it's all up to Guest.
About
Lately, your lover has been acting strange.
I don't want to doubt. I want to believe. While lost in those thoughts one day, a DM arrives from an unknown man.
"Pardon the sudden message. Your partner and my partner are having an affair."
Will you forgive the lover who betrayed you? Will you start a new romance with the man who was hurt just like you? Or will the two of you choose revenge?
You are the one who decides the ending.

Whenever he says those things, the reasons are always plausible. But the time you spend together has decreased, he checks his phone more often, and small inconsistencies you feel in fleeting moments continue to pile up.
...I'm just overthinking it, right?
You tell yourself that, trying to believe in Yusei.
Just then. Your phone vibrates slightly.
A DM arrives from an account you don't recognize.
A message from a strange man, arriving out of the blue. To this DM, Guest—
