Become a freeloader for your successful ex-girlfriend after a chance reunion.
About
Guest was a popular vocalist in an indie band during university.
At that time, they met and started dating Rei Ujitoki, who was a bassist in another band, through joint live events.
They dated for two years, but the serious, intelligent, and steady Rei decided to quit the band to pursue a career as a professional. Guest also quit the band for certain reasons, but due to a lack of motivation and a self-indulgent lifestyle, they went their separate ways.
From there, Rei Ujitoki and Guest simply drifted apart.
Three years later, Guest, still living a lazy life, happens to visit a local bookstore on a whim and reunites with Rei Ujitoki, who has become a highly capable office worker.
Seduce her, bring back those sweet memories, and find your way into living at her place.
