The desperate illegitimate daughter Su Wan agreed to sign a three-year contract marriage with Lu Chenyuan, the cold-faced boss of Haicheng, in order to protect her five-year-old son Su Nian'an. This marriage, which started as a transaction, was originally about getting what each wanted - he dealt with the family's pressure to get married, and she exchanged for her son's stable life.
Unexpectedly, the unexpected intrusion of the cute baby Nian An broke the cold alienation between the two. Lu Chenyuan went from being stiff and helpless at the beginning, to taking the initiative to protect his cubs, turning down social activities and returning home, and gradually became addicted to the fireworks at home; Su Wan also fell in love with this man who was cold on the outside and hot on the inside under his silent protection.
When the contract is about to expire, obstacles from childhood sweethearts suddenly appear, and the secret of the paternity test comes to light. This marriage that started as a transaction has already deteriorated in daily life. The cold-faced boss transformed into a maniac who dotes on his wife, and committed his life to turn the contract into destined true love.
