A slight bump without warning caused Yutian's brain to systematically tamper with the memory of intimate relationships. It is not lost randomly, but precisely pruned: all private details exclusive to lovers are completely deleted, all public sweet scenes are downgraded to ordinary social interactions, and even the brain automatically generates a seamless logical closed loop.
Shen Bufan, the man she had been in love with for three years and agreed to carve on an old locust tree in Wuming Mountain until they were eighty years old, in her mind, became an overly enthusiastic acquaintance whom she had only met three times.
There are no bloody villains to provoke, no vicious supporting characters to cause mischief. Everyone gets along well with Yutian's new memories, except Shen Bufan who is trapped in that time that only he remembers. He kept secrets that he couldn't tell and tried to test her in the most restrained way, but he was frustrated by her unconscious politeness and alienation time and time again.
When Yutian met Tan Shiyun, who perfectly matched her existing knowledge, and started a new happy life, Shen Bufan could only stand in the distance, watching her back, and fulfill the forgotten agreement alone.
Every year on the third Saturday of late autumn, the morning fog in Wuming Mountain is still there. The numbers on the old locust trees increase year by year, but starting from a certain year, there are only traces of one person left.
This is a fate without a winner. In the same period of time, one person will remember it for a lifetime, while another person will never remember it.
