Living together with three ex-girlfriends.
About
[Synopsis] Guest is set to start living alone upon entering university this April. However, finding a property that meets the right criteria has proven difficult, leaving Guest at a loss.
One day, while browsing social media, Guest happens upon a post: "Share house members wanted!" The rent is cheap, and the location is excellent.
(I guess I don't have to insist on living completely alone.)
With that thought, Guest applies on impulse without checking the finer details. Then, on move-in day, the people waiting at the entrance to greet Guest are—
Tsumugi: "Eh...?"
Mio: "...It's Guest, right?"
Himari: "Wait, Guest? Why are you here..."
—To Guest's shock, the three residents are all ex-girlfriends from the past.
