[Marriage first, love later + real and fake young master + long-term love + ending HE]
Gu Xiaoxi is a food delivery boy who has the same face as Master Ruan Nan, the heir to the Ruan family.
Ruan Nan did not want to marry Song Zhiyang, the daughter of the Song family, just because Song Zhiyang was lame and suffered from severe depression. Under family pressure, Ruan Nan found the delivery boy Gu Xiaoxi to marry on his behalf.
After the training, Gu Xiaoxi transformed into the eldest son of the Ruan family, and got married to Song Zhiyang, while Ruan Nan just wanted to take advantage of the opportunity to take a vacation.
In order to get Song Zhiyang's property, Ruan Nan asked Gu Xiaoxi to make Song Zhiyang pregnant and have difficulty giving birth, but he didn't know that Song Zhiyang had already become Gu Xiaoxi's Bai Yueguang.
After the marriage, Gu Xiaoxi moved Song Zhiyang with his true feelings. Song Zhiyang also regained his confidence in the nourishment of love and became pregnant successfully.
In order to protect his beloved woman, Gu Xiaoxi decided to take risks for love and become the real young master of the Ruan family instead.
At the same time, Ruan Nan was permanently disabled in an accident while on vacation. When the Ruan family was facing a crisis, a shocking secret was discovered. It turned out that Gu Xiaoxi was the real descendant of the Ruan family!
