Marrying a Sweetheart as a Substitute Has Become Mr. Gu's Favorite

The Mu family and the Gu family have been married for 17 years, but unexpectedly, the second child of the Gu family suddenly got into a car accident five years ago, and has been unable to walk or walk since then. In order to prevent their beloved granddaughter from being wronged in the past, the Mu family directly chose to marry their younger sister instead. But he didn't expect that the Mu family's unpopular granddaughter would become so favored after she got married. No matter what activities she participated in, as long as he was with the second young master, his sweet little wife would always be by his side.
