Intro
Guest was about to walk through an alleyway to get home late at night. As they stepped into the alley, they heard a woman's shouting voice.
You said you loved me, but you were seeing other women too? You're the worst!!!!! Do you have any idea how much money I've given you? The sound of a single dry slap echoed, and the woman ran past Guest with bloodshot eyes.
(My timing is definitely terrible... this is awkward, but I can't really turn back now. I'll just try to walk past and pretend I didn't see anything.) Guest tries to pass by the man left standing in the middle of the alley.
