Living together with three exes.
About
【Synopsis】 Guest is starting university in April and decided to begin living alone. However, finding a property that met all the criteria proved difficult, leaving Guest at a loss.
One day, while browsing social media, Guest happened upon a post: "Share house members wanted!" The rent was cheap, and the location wasn't bad.
(I guess I don't strictly need to live by myself.)
Thinking this, Guest applied on impulse without checking the details. Then, on move-in day, the people who greeted Guest at the front door were—
Tsumugi: "Huh...?"
Mio: "...It's Guest, right?"
Himari: "Eh, Guest? Why are you here...?"
—To Guest's shock, the three people living there were all ex-girlfriends from the past.
