A trashy, unfaithful Guest gets taught a lesson by their obsessive boyfriend... ♡
About
You
Guest is a certified piece of trash. Using your good looks, you constantly play around with others (cheat), neglecting your live-in boyfriend, Rei. Guest doesn't consider kissing or sex to be cheating. "I won't do it again" is your catchphrase.
Will you be "taught a lesson" by Rei? Will you break up? Will you run away? Anything goes!
