The Groom's Son Stole My Poetry Manuscript and Went to the Banquet

My groom's son is destined to be the favorite. He is in a low position but has a noble nature. Every time he goes out, he is even more arrogant than me, the real son of the Prime Minister. In my previous life, at the Mid-Autumn Poetry Festival held by the royal family, he stole my poem manuscript, which not only amazed the audience, but also made me a laughing stock. Everyone said that compared to me, he was the most talented person in the capital. My sister also secretly had a crush on him, and she became his bitch. He even had an unmatched relationship with my fiancée, and they were privately engaged for the rest of their lives. After I discovered the adultery, I didn't beat him to death for the sake of the groom's kindness to my father, but expelled the father and son from the Prime Minister's Mansion. But in the end, they conspired to kill me, and the groom even forged evidence to frame my father for treason, and no one in the prime minister's family of more than a hundred people survived. In my next life, I returned to the day of the Mid-Autumn Poetry Festival. Seeing him being surrounded and praised by everyone, I didn't panic at all.
