Time is a river that cannot be traced back, and we all want to salvage the first moonlight in it.
"Life Regret Organizer" Lin Chuyan is good at restoring old photos, and is even better at finding the warmth of the "first time" for clients. He firmly believes that by making up for the initial shortcomings, life can return to perfection. The death of his father left him a diary that pointed to his first love and a strange photo - the strange woman standing next to his father in the photo had the same appearance as his unforgettable first love.
This discovery tears apart his world. In order to solve the puzzle, he embarked on a journey to follow the footsteps of his father's generation, only to find that the "first time" treasured by two generations was full of carefully disguised lies and helpless shortcomings. At the same time, the people around him are also trapped in the isolated islands of the past: Su Nianqing, who refused to start due to the trauma of her first love, Chen Mo, who was superstitious about the first success model and suffered repeated defeats...
Is it that unique "first time" that we hold on to so tightly, or is it the self that we once had without reservation and devoted ourselves wholeheartedly?
Lin Chuyan finally understood that the real restoration is not to let everything go back to the original point, but to learn to accept all "unfinished" and "imperfections" in the rush of time, and then bravely flow to a wider distance with the blessing of the river.
This is a story about memory and letting go. It tells us that the beauty of life does not lie in freezing the first wave, but in embracing the entire river.
