The Heir Who Refused My Treatment Became Barren

This was the second time I lived this life. I was the last descendant of the serpent-kin. I treated men’s fertility issues and other similar problems. In the previous timeline, my adoptive parents chased me out of the house as a way to appease their true daughter, Cynthia, that they had reunited with. Lester Ward offered me his company’s shares and a luxury mansion to persuade me to marry his grandson. His only condition was for me to cure his barren grandson, Matthew Ward. In the end, I did so, and Matthew married me. However, on our wedding night, he forced me to reveal my serpent-kin guise and show him my tail. Then, he extracted my scales and sold me to a red-light district abroad. Only then was I made aware that he had been having a secret affair with Cynthia this whole time. “You’re just a greedy beastfolk who wants the matriarch position of the Ward family! Cynthia is my true love. I was cured when I slept with her. You waited in my room all this time just to pretend to treat me! Cynthia thought that we were really together and ran off. In the end, she was killed by some fiends! Aren’t you a serpent-kin? Your kind is loose and immoral. Well, you will die here in this den of iniquity!” I closed my eyes and waited for death. However, when I opened my eyes again, I found myself back in time at the moment Lester came asking for my help. I waved him off. “Your grandson’s condition is a curse, not a medical affliction. No one can treat him.”
