Su Yue is thirty-five years old and a strong woman in an advertising company. She is about to be promoted and her wedding is approaching. But an accident happened on her birthday, and her body returned to that of an 18-year-old - her boyfriend turned around and broke up with her, rumors spread in the workplace, and her promotion quota was removed.
She was forced to return to campus to "re-read her youth", but met Lin Yu, a junior student who was 10 years younger than her. Others only regarded her as a freshman of the same age, but only Lin Yu saw her unconcealable maturity, calmness and sharpness.
She wanted to draw clear boundaries, but he used firm choices again and again to pull her out of "I am not worthy of being willful anymore". Doubts from the outside world, opposition from parents, and secret identity are like time bombs - but Lin Yu said: You are not going back to eighteen, you finally have a chance to live for yourself again.
She restarted her life and started her own business, while he wrote "love hard" as his lifelong answer.
