[Chinese]JUQ-859 "I have no experience with the sex industry" said my fiancée, but her technique is so good that I'm constantly suspicious and paranoid. Mahiro Ichiraki.

Yuzuru, the eldest son of a kimono shop that has been in business for 150 years, is engaged to Mahiro. To marry into a prestigious family, she must be approved by her strict father. Beautiful, healthy, and pure Mahiro is supposedly the ideal bride… but in reality, she has another face as the legendary number one hostess 'Rika-chan' for two consecutive years. This fact must never be found out. To appeal to her sense of chastity, she doesn't have sex until marriage, only up to the last moment... However, the battle-hardened Rika-chan (Mahiro) unconsciously showcases her 'amazing technique.' Yuzuru begins to suspect Mahiro, and her father hires a detective to investigate her background... What should be done??
