After exchanging marriage with my elder sister, I won with a bad hand.

Shen Yihuan was reborn, and when she was still a little confused, her elder sister proposed to exchange marriages with her. Only then did she know that her elder sister was also reborn. In her previous life, she married the humble Tenth Prince, and went to her fiefdom to suffer after marriage. No one expected that she would turn things around a few years later. The Tenth Prince became the emperor, and she became the queen. Everyone envied her, and her elder sister was even more jealous. Because her elder sister married the prince, thinking that she would have a bright future, but the prince turned out to be useless. Not only did he lose the throne, but he was also a playboy, and he was dying for a woman all day long. This time she was reborn, how could she not seize this opportunity? Exchange marriages, must be exchanged...
