The first encounter between Lin Yumo, a freshman in the art department, and Wen Huasheng, a top student in the medical school, started with a misunderstanding and fainting, but by a trick of fate, they became neighbors and the sons of family friends. The secret concern of the indifferent senior, the heartbeat in the studio on a rainy night, and the passionate confession under the starry sky tightly connect the two hearts. However, the old scars on Wen Huasheng's wrist and the "old friends" relationship between the two families that were kept secret from their parents are like undercurrents of icebergs.
The sweet façade collapsed after a family dinner. Lin Yumo accidentally glimpsed a strange confrontation between his father and Wen Huasheng about the "experiment back then", and then encountered Wen Huasheng's decisive breakup and disappearance. Lin Yumo, who was looking for answers, learned a shocking secret from his father: twenty years ago, his fathers, who were neuroscientists, actually used young him and Wen Huasheng as memory transplant experiment subjects. An accident caused part of Lin Yumo's memory to be overwritten by Wen Huasheng, and he witnessed a "terrible scene" that could destroy his mind. The two families broke up and his memory was deliberately sealed.
Memory fragments hit Lin Yumo's cognition like a tide - those inexplicable familiarity and the promise under the pear tree were not hallucinations. When he questioned Wen Huasheng, the other party painfully admitted that he always knew the truth, and he was even more afraid that Lin Yumo's feelings originated from the implanted memory fragments of "himself". The deeper fear is that the fathers' experiment has never really ended, and their love may become the trigger for a restart.
In order to protect Lin Yumo from harm and the threat of restarting the experiment, Wen Huasheng once again chose to escape. But this time, Lin Yumo was no longer a passive memory carrier. He sneaked into the dusty archives, pieced together the horrifying records of "Special Project-X" from clues, and received a mysterious invitation from Wen Huasheng's sister Wen Ya - a bigger secret of life and death unknown even to Wen Huasheng, waiting to be revealed. When memory becomes a carefully woven cage, can Lin Yumo regain his tampered life? Can he and Wen Huasheng break free from the fate of being entangled in experiments and find the true each other in truth and lies, sacrifice and redemption?
Purpose: Under the artificially tampered memory and the heavy family fate, the individual's tenacious pursuit and struggle for the true self, sincere emotions and destiny autonomy.
