Before Dying, My Wife Was Writing a Love Letter to Her First Love

I found the stack of yellowing love letters in the cracked floor tiles of the old house. The paper is suffused with moisture and was written by my wife, a writer. I finally know what my wife has been writing secretly while sitting in the study with me every night for more than 20 years. He told his lover about his endless love, and every time he received a reply, the person who replied was the first love he couldn't love when he was young. Looking back on most of my life, I spent daily necessities and taking care of my children. Before he died, his wife was writing poems for her lover. He never wrote a single love letter to me. When he learned that I was dead, he burned one after another at my grave.
