This is the Madonna bachelor dormitory, currently fully booked ~Rin's lone struggle with the big-breasted dormitory mother~

Rin, who lost her job as a temporary worker and was kicked out of her boyfriend's apartment, is tired of the coldness of the city and finds a job as a live-in dormitory matron. The people living in the dormitory are boring people such as Koshinzuka, who keeps failing exams, Takinogawa, a shut-in, and Arakawa, who is unemployed and in the middle of divorce mediation. Meanwhile, Rin is struggling alone, but her ex-boyfriend (who actually has a child) asks her about it... Today as well, Rin will heal the dormitory with her bright and naughty feelings while making her huge breasts bounce as she endures her lonely feelings!
