Rieko lives with her son while paying the debt left by her deceased husband. Life is hard and I have been in arrears of rent for three months. The landlord, Sagawa, was reminded every day. - If Sagawa accompanies her hobbies, she will be given a condition that she will wait for the rent, and Rieko accepts it for her son for the rent. However, his hobby is "bondage". Rieko, who was obscenely tied up at Sagawa's behest, was tossed with the ripe flesh skin that the rope deeply cut into as she wanted.
