I'm so Angry, My Eldest Sister, the Heir Apparent You Didn't Want Became the Throne After Marrying Me.

In her previous life, Ruan Xinchen was forced by her aunt to marry into Prince Zhan's palace on her sister's behalf. I thought she would be a widow after getting married, but the King of War, who had been in a coma for seven days, came back to life. After that, he doted on her even more, and the couple sang in harmony. And Ruan Yihe, the eldest daughter of the Ruan family who was supposed to bring joy to the King of War, married the Crown Prince Gong. But who would have thought that the noble and handsome prince was actually a lunatic. Less than three years after their marriage, he accidentally pushed her into a lotus pond and drowned when he went crazy. The two sisters were both reborn, and when they opened their eyes again, they returned to the day when the Queen Mother sent them to the Ruan Mansion. My sister Ruan Yihe cried with joy and choked with sobs: "Father, mother, the King of War is the hero of the Chu Kingdom. I am willing to marry him." Sister Ruan Xinchen was ecstatic. 'Great, my vicious sister-in-law is going to marry a scumbag. ' Wait, it seems like the prince she is going to marry is a lunatic? The Queen Mother thought about how to kill their whole family every day. The Crown Prince: "Madam, don't panic, the old woman is dead, and her husband has gone crazy and is on the throne."
