Vitamin's manufacturer concept is to "embodiment actresses' desires, their erotic dreams, and their fantasies..." The main character this time is Miu Harutani. She seems to have been obsessed with eroticism for a long time. Her desires are to be tied up! To become a masochist! To enjoy Japanese SM play in the style of Dan Oniroku! Let's make those wishes come true as much as possible through a drama... (Synopsis) Ichikawa Bokutaku is an old man who once dominated the world of ink painting in Japan. His popularity has waned and he now lives a reclusive life. In his apartment, his beautiful assistant Miu (played by Miu Harutani) takes care of him. The relationship between the two has been "lovers" for a long time. However, Ichikawa suffers from erectile dysfunction due to the stress of a busy life at the height of his popularity. His mental health also breaks down, and his sexual tendencies become severely distorted. He is an abnormal sadist. Moreover, he gets excited by the sight of his beloved Miu being beautifully tormented by another man without getting his hands dirty. However, he does not get an erection. The ultimate cuckold love. The more Miu gets aroused, the more satisfied she is, and she believes she can create a better work, so she continues to paint new pictures every day. However, the world doesn't pay her any attention... Miu is a single ex-office lady. She was captivated by Ichikawa's ink paintings, who was once at the height of his popularity, and when she handed him a fan letter at an event, Ichikawa immediately contacted her. They became lovers, but Ichikawa, who eventually became mentally unstable, broke up with her. However, she believes in Ichikawa's recovery, and lives in his house, devoting herself to him 24 hours a day. This was because she herself was seeking Ichikawa's perverted sexual habits. "Today too...I want you to punish me..." Miu is already tied up on the bed. "Oh, what a good expression. You can't move. You can't move no matter what you do to me." Ichikawa tickles her armpits and nipples with a brush. Miu writhes in agony. "Isn't she cute? Okay, Hatakeyama, keep going. I'll draw." Ichikawa's pupil Hatakeyama, who adores him, blames Miu. He draws her fleeting orgasmic state into a sumi-e painting. This is Ichikawa's current lifestyle.
