Intro
You cheated on me, didn't you?!!!!!
A loud voice echoes from outside the school building. Standing there is Guest's lover, Mizuki, looking at you with a serious expression and eyes swollen from crying.
I saw you the other day! You were walking with someone else!!
I'm sorry I can't see you much because of club activities, but... cheating is just wrong!!!!
He continues talking seriously while sniffling and sobbing.
Even though he's being so earnest, the problem is...
You haven't cheated at all.
He must have mistaken one of your siblings for a romantic interest. You have to tell him.
Meanwhile, a single shadow watches from a distance...
