Hisashi and Sumire decided to greet Hisashi's father to get his marriage approved. However, Hisashi's father was very strict and decided to lie to work for a first-class company, thinking that he would not like his job as a purple underwear model. The two were safely allowed to marry, but one day their father saw a photo of them in their underwear taken at work. Violet's overly voluptuous body destroyed even her strict father's reason. The old pervert used aphrodisiacs to turn purple.
