Marrying My Scumbag Ex's Elder Brother With ED

In her previous life, An Yi's stupidity caused her to enter the wolf's den after escaping from the tiger's den. The scumbag helped her deal with her scumbag father's family, but took over her mother's family inheritance, causing her to lose everything. He even cheated on her while she was pregnant. An Yi died from childbirth, and the first thing she did after her rebirth was to find the scumbag's arch-enemy slash elder brother. She stared at his handsome face and proposed a deal. "I heard that you have ED, and I'm the best urologist around. If you make a deal with me, I'll help you become a normal man." "…" Yi Yu's pale face flushed red. "How can there be such a shameless woman like you?" An Yi raised her hand and tugged at his belt. "A doctor has a heart of a parent. What's there to be embarrassed about in front of your own parents?"
After they got married, An Yi used the advantage of knowing what was coming and her superb medical skills to collaborate with Yi Yu. She fought against her scumbag of a father and her scumbag ex! The rich ladies who mocked An Yi were both angry and jealous of her. Why was her life getting better? The ladies said, "Heh, so what if she's rich? She's just married to a man with erectile dysfunction. She won't be able to enjoy the happiness of a woman for the rest of her life!" At night, Yi Yu familiarly unbuckled his belt after An Yi took her bath. "..." An Yi turned her face away from him. "You don't need treatment today." Yi Yu climbed onto her body. "You said it yourself. A doctor has the heart of a parent. What's wrong with a parent looking at me more than once?" An Yi muttered, "How can there be such a shameless man like you?" Three hours later, An Yi rolled off the bed in a sorry state. "Yi Yu! You big liar! You don't have ED at all!"
