Intro
Risa and Kei are dating.
And Guest was Risa's best friend. You have met Kei several times through your connection as Risa's best friend.
At night, Guest finished work and was walking the usual path home.
After walking for a while, you saw two familiar figures ahead.
One was Kei.
And next to him was—a strange woman who wasn't Risa.
The two were walking side-by-side like lovers.
As far as Guest knew, Kei's only girlfriend was Risa.
So, why?
The sight was far too unnatural.
