A coquettish fisherman's daughter ✘ a cold, scheming prince

Jiang Shangge was the founder of a jewelry brand. One day, she transmigrated into the role of a vicious supporting character, while the heroine was the fake heiress, Jiang Muyun.

Jiang Shangge was the real daughter, raised in a fishing village. After her birth parents and brothers took her back, they still favored Jiang Muyun. Jiang Muyun was also the emperor, Gu Xingchao's, first love. Jiang Shangge was merely a cannon-fodder stand-in, destined to be buried alongside the emperor after his death, while Jiang Muyun would eventually rule from behind the curtain with the young ruler.

After transmigrating into the book, Jiang Shangge helped her adoptive parents prosper by collecting pearls. This time, she planned to stay far away from Gu Xingchao and expose Jiang Muyun and her brother's hypocrisy to her birth parents. She never expected Gu Xingchao to fall in love with her.

Jiang Shangge had no intention of meeting a tragic end as a burial sacrifice, so she had no choice but to take Jiang Muyun's place and marry Prince Qin, Gu Xingmian, one of Jiang Muyun's cannon-fodder admirers.

After the wedding, Jiang Shangge remained out of favor and had to contend every day with the many concubines in Prince Qin's household who were all Jiang Muyun's stand-ins.

Gu Xingmian was infertile and had lost his right to inherit the throne. As a medical student, Jiang Shangge was able to cure his infertility. After a night of drinking, they conceived a child, the emperor's eldest grandson, and from then on they couldn't stop, eventually having three children in a row.

Gu Xingmian rose in status through his children. Though he had always been a hidden dragon waiting to rise, with Jiang Shangge's help he deposed Gu Xingchao.

Jiang Muyun had not left the Eastern Palace, and Jiang Shangen realized she was still just a stand-in. She left a letter of divorce and fled with their three children and the baby in her womb.

Gu Xingmian panicked and searched everywhere for her like a madman.
