After the Marquis Was Reborn, He Was Forced to Regret His Marriage

I am the old Marquis of the Changning Marquis Mansion. I have lived a life of a wife, a virtuous son, and a filial piety. Everything goes well and I consider myself happy. Unexpectedly, when the deadline was approaching, I heard the truth that my wife had hidden for sixty years: She said that she didn't love me at all, and even hated me very much. She said that if it were not to pave the way for her natal brother, she would have left with her sweetheart long ago. Only then did I find out that her sweetheart was killed in a fight for favor after becoming a princess. Reborn and returned to the year when we first met, this time I did as she wished. When she accidentally fell into the water, I kicked her sweetheart into the lake.
