Her whole life has been crazy: the national idol, dream lover, and the most beautiful man Bai Huachen was actually the one she was to marry! Marriage! Husband! Bai Huachen: "... Does my life have to be ruined just like this?" Mai Mengmeng: "Am I that bad!" The emperor's sweetheart, the eight-year-old second prince, regarded her as his love rival! The second prince: "If you don't leave, I'll kill you! She promised to be my princess when we were playing house!" Mai Mengmeng: "Your Highness... I don't like women... Besides, can what I said count?" These, too! At once! Calculate! Got it! Why is love so unreliable? ! ! Beautiful man Bai Huachen: "In order to cultivate your self-consciousness as a man, I will marry you and stop harming others." Local tyrant Lin Yu: "Bitch, I'll give you all the money in the bankbook and go back to me!"
