Lu Zhaoyan, the president of Lengjun Technology, has a mechanical heart beating on his left chest, but his fatal weakness was discovered by the genius connoisseur Jiang Yubai at an auction. On a rainy night seven years ago, an anonymous painter stuffed the sick young CEO with life-saving medicine; when they met again seven years later, Jiang Yubai saw a hidden medicine bottle hanging on a silver chain around his neck, and the bell bracelet concealed the charging key of the mechanical heart. When Lu Zhaoyan discovers that young people can see through all fake paintings through iris mutation, his half-brother's fake conspiracy is spreading radioactive poison all over their wedding rings. This kiss that started with the heartbeat returning to zero will eventually use the mint scent that has been dried in the medicine bottle for seven years to unlock the two-way redemption buried in the painting "Mechanical Heart".
