In the "Xinghai City" where the neon lights are flashing but people are alienated, there is a "Time Rental Shop" hidden deep in the old alleys - it does not rent home appliances or houses, but only rents "forgotten fragments of time". The owner, Lin Wanxing, is a tech nerd with his own "Social Fear Buff". He can use his ancestral old pocket watch to extract the warm fragments lost in daily life, but he cannot read his own past. Until one day, Su Chen, the "king of books", bumped into the store door. With dark circles under his eyes, he asked for "thirty minutes of morning light without being disturbed by work," but he accidentally triggered an abnormal reaction in his pocket watch - the shadows of the two people overlapped in the fragments of time and became what they looked like ten years ago. With each wonderful time rental, Lin Wanxing discovered that Su Chen's "workplace anxiety" hid secrets related to herself, and that old pocket watch was quietly twisting two seemingly parallel lives into a destined bond. While they were complaining and cheering each other in the "daily life of social animals", they uncovered the truth in the fragments of time. It turned out that the so-called "rented time" was just the "countdown to reunion" that fate had already reserved for them.
