Smile Life Home, an assisted living facility for the elderly with paid care services. The facility has many male residents and is quite homey. A young and cute caregiver, Ren, started working there. She diligently took care of the elderly, but they began to imagine lewd things about her. They threaten her with 'medical misconduct' over a minor mistake. The honest girl is shaken by the words and ends up being molested by those old men. The old men who have given up on their short lives are escalating in their lewd and obscene acts day by day, and the pitiful life of Lotus, who is constantly raped, continues today as well.
