28-Year-old Lin Yan, the "idle heir" of the family group, privately runs a top architectural design studio. On the surface, he is a dandy, but on the inside he is suffering from the death of his best friend Su Zhe. After learning that Su Zhe's heart had been transplanted to 25-year-old emergency doctor Jiang Yichen, Lin Yan approached with obsession.
Jiang Yichen, who was born in a small town as a topic writer, has a strong sense of responsibility and is initially disgusted with Lin Yan's playfulness. While getting along, the two broke through class differences and family pressure. After a misunderstanding and conflict, Lin Yan recognized his true feelings and changed for Jiang Yichen. Deputy CPs Shen Chi and Wen Miao also provided sweet assists. In the end, they let their two hearts resonate at the same frequency and gained love.
