After the real daughter returns, the fake daughter Su Nian is considered an outcast by her family and is forced to marry the Gu family's sick young man who is rumored to be "paralyzed, disfigured and in intensive care" instead of the real daughter. On her wedding night, she discovered that this legendary "living dead" could not only stand and walk, but also had a body as strong as iron. He only chose to disguise himself to avoid assassinations within the family to seize power. The two hit it off and signed a fake marriage agreement: Su Nian needed the identity of the young mistress of the Gu family to slap those who looked down on her in the face, and Gu Yeting needed a wife who was transparent to the outside and shrewd to the outside to act as a cover-up. From then on, Su Nian took the fake marriage certificate and started doing various cool things - just after being ridiculed at the banquet and losing his job, he turned around and showed off his talent in top jewelry design; just after being ridiculed for climbing a high branch, he immediately used Gu's capital chain to backhand the other company. During the day, she is pretty and smart, pursuing her career, but at night... She has to help this fake husband "heal". Until everyone suddenly realized that it was not Su Nian who had climbed up the Gu family, but the entire wealthy circle who should look up to her.
