A beautiful and independent female protagonist × a cold-hearted male protagonist who is actually a love-minded man
(Shuang Jie!! The male protagonist fell in love with the female protagonist at first sight, and the male protagonist also traveled through time.)
Xu Zhi found that when his grandfather was alive, he would often sigh unconsciously when he looked at her, and when he was dying, he said to her, "I'm sorry?!" Xu Zhi got into a car accident because of his uncle's troubles. When he woke up, he found that he had become his grandfather's sister?! Because the Xu family's business was targeted, Xu Zhi became Gu Suisui's wife in order to get help from the Gu family.
But, why do these people from the Republic of China look exactly like people from the 21st century?
Xu Zhi: "My marriage to you is a family marriage. I hope we can both understand."
Gu Suizhi: "Yeah, yeah, I don't care what kind of couple you are, we both have to sleep together if we have the same certificate."
Xu Zhi: "..."
Love brain is a must.
