Ordinary girl Lin Xiaonian, unable to bear her family urging her to marry, went out to find a job to escape intensive blind dates. By a twist of fate, she entered the Lu family to take care of Lu Xingxing, a little girl lacking a sense of security. To give the child a complete companionship environment, she and group CEO Lu Chenyuan entered into a contract marriage. Originally an agreement where each took what they needed, true affection grew during their days and nights together. Xiaonian used patience and kindness to heal the inner wounds of the child, and also insisted on self-growth, founding a parent-child studio to realize personal value. Lu Chenyuan slowly came to understand the meaning of family, learning to shed his cold shell to protect his family.
