In Shanghai, medical aesthetics prosthetist Lu Chenzhou has a secret: every truth he speaks will make his lips grayer - until one day, he will no longer be able to speak any truth.
Six years ago, his wife Su Wanqing left him driven by a lie. Six years later, she suddenly appeared at the door of the clinic, bringing a name: Chen Muye. A person who used other people's lifespans for experiments, an old classmate of Lu Chenzhou, and the last person his mother saw before she died.
Following this clue, Lu Chenzhou walked into a secret that his mother had foreseen but never told him - she once had the same ability and spent the same price. She left behind a letter, a bracelet, a minute and seven seconds of silent recording, and a dry osmanthus branch.
This is not a story about ability. It is a story about "what words must be said, and what words once said can never be taken back".
In the end, Lu Chenzhou did not choose inheritance, revenge, or silence. He just put the lip balm that his mother had used up in his pocket. Keep living.
