Nurse Yumi's hospital admitted Sakuraba, a patient with a severe hernia. After his surgery ended in failure, leaving him immobile, Yuka devoted herself to nursing him back to health.

He made Yuka tend to his every need, from feeding him to attending to his personal hygiene, and eventually took advantage of her body to satisfy his sexual urges.
