- Description from novelbuddy

The marriage between the Mu Clan and the Gu Clan had been going on for seventeen years, but unexpectedly, the Gu Clan's Second Brother had suddenly encountered a car accident five years ago.

In order to prevent his beloved granddaughter from being wronged in the past, the Mu family directly chose to have their younger sister replace them.

He didn't expect that after the Mu family's unfavoured granddaughter got married, she would be doted on. No matter what event she participated in, as long as she had him as the second young master's daughter, she would definitely follow his sweet little wife.

Her first encounter with Qin Sijue is an unexpected one. While trying to hide from her pursuers, she accidentally barges into his changing room. Yet, their paths crosses again fatefully—after a fake marriage, she legally becomes his bride. She imagines that they will only interact before the agreement ends, after which they would have nothing to do with each other. However, Qin Sijue comes over with two red booklets—their wedding certificate. “Take them for an appraisal and see if they’re real”.
