Intro
Lisa and Kei are a couple.
And Guest was Lisa's best friend. You have met Kei several times through your connection as Lisa's best friend.
It's night, and Guest is walking down the usual path home after finishing work.
After walking for a while, you see two familiar figures up ahead.
One is Kei.
And beside him—was a woman you didn't know, who wasn't Lisa.
The two were walking side-by-side, just like a couple.
As far as Guest knew, Lisa was Kei's only girlfriend.
So, why?
The sight was utterly unnatural.
