My wife and I have been married for four years. I am the husband, and we've been living together as a married couple. After my wife's biological mother passed away, her mother came to live with us, forming a household of three: my wife, myself, and my mother-in-law. We got along well with her, and I truly felt the bond of family. But one day, I discovered my father was having an affair with my mother-in-law. From the moment I stood frozen in shock, our family bond was completely shattered.
