A lame man, Wang Yu, married into the Liu family five years ago. Five years ago, Wang Yu accidentally saved Liu Xiaoyue from committing suicide by jumping into a river. However, he was bitten by a water snake in the river, leaving him with a lifelong disability.
Liu Xiaoyue repaid her with her own life and married Wang Yu regardless of her family's restraints.
Therefore, Wang Yu became the Liu family's son-in-law.
