A few days of training diary to raise an apprentice obedient maid to my liking.

A middle-aged man who has achieved success at work. He lives in a magnificent mansion with money, but his wife evaporates with a young man and spends his days alone. The betrayed man's eyes are empty and like glass balls... A man who can do nothing but work decides to hire a maid, but an innocent, pure and beautiful girl appears and develops an abnormal sexual excitement, and trains her to become an absolute and obedient maid that she likes and dyes her. Riko is a pervert that escalates day by day...
