After Being Abandoned by My Brother-In-Law, I Became an Andrology Expert

Jian Jian lived a life worse than a pig or a dog until Lou Yu took her in. But she fell hopelessly in love with him. Unfortunately, he was getting married and ruthlessly sent her abroad. In order to take revenge, she studied andrology. After returning again, she became the most famous andrology expert. Specialized in treating impotence, premature ejaculation, infertility... This time, Lou Yu blocked her in the bedroom: "If you want to see a man so much, you might as well show him to me." She smiled evilly, and used her hands to unbuckle his belt: "No wonder I have a fiancée and never get married. It turns out it's not possible." "Okay, do you want to try it?" "No, you'd better go and harm others."
