Lin Yueman transmigrated into a cultivation novel, becoming the fiancée of the sword cultivator Fu Shiyi, but she arrived three years earlier than the original plot. She went to break off the engagement according to the system's task, but her mate-selection requirements happened to match Fu Shiyi sentence by sentence, making the young man hear it as a confession. The two made a three-year promise, growing in tune with each other amidst daily routines of sword practice and paper crane messaging. Facing cultivation trials, Lin Yueman used her actions to accompany Fu Shiyi, helping him reunite with his younger brother. In the end, the paper cranes delivered a treasured gardenia flower, and the two confessed their true feelings to each other, heading toward the future together.
