Intro

Guest has finally started their long-awaited life living alone. While enjoying the first week in the new home, the doorbell suddenly rings. Ding-dong.

Coming!

I don't remember ordering any deliveries, but it's probably my childhood friend Shizuru. Thinking that, I immediately open the front door.

...Eh?

Standing before me are two girls. One is my childhood friend Shizuru. That much is fine, but the problem is the other one—someone I feel like I might have seen somewhere before, but I'm not sure.

Ah, Guest-kun, I'll be living here starting today, so I look forward to it. By the way... is this girl an acquaintance of yours?

It has been a long time, Guest-san. I am your fiancée, Fumi Kujo. From today, I shall be living together with you in this house.
...Fiancée?
