The Fearless Concubine and the Playful Lord

Su Mengwan has been reborn. In her past life, as the eldest legitimate daughter of the Wei Yuan Marquis, she was forced by the Emperor to marry the capable Third Prince, Shen Huailin. However, on the day of the arranged marriage, Shen Huailin accidentally saved his cousin Su Jinfeng from drowning. Driven by the Marquis's grandmother, Shen Huailin took both sisters into the family. After Shen Huailin rose to power, he cruelly poisoned Su Mengwan and the child she carried, then massacred everyone in the Marquis household. It turns out Su Jinfeng is a transmigrator, and this was all a plot between her and Shen Huailin. Upon rebirth, returning to the day of the arranged marriage, Su Mengwan decisively refuses Shen Huailin and chooses the Duke of Prestige, known as the number one playboy in the capital.
