【Window Kingdom】A summer memory with my sister’s friend

synopsis
One afternoon. I was lounging in the living room of my parents’ house.
The doorbell rang. The identity of the sudden visitor was my sister’s friend, Kotone Mizuno.

I’ve never seen a girl I haven’t seen in a few years, but she has grown into a beautiful woman.
I’m going to just keep her company until my sister gets home, but my relationship with her is taking an unexpected turn.
