Iwasaki Takuya wakes up in the hospital after an accident. His sister-in-law Haruka was working there as a nurse. The doctor in charge of him was Reika, an older sister from his old neighborhood, one he had longed for a long time.

During his stay he met another patient Saya, who had been hospitalised for a long time. He also met Saya's mother Kaname, working at a coffee shop near the hospital.

Thus began his immoral hospital life surrounded by women.
