In the quantum cloud beyond the multiverse, gardener Lin Shen guards the quantum rose that symbolizes the memory of love. A "lovelorn syndrome" plague has broken out across all parallel universes. Life has lost the ability to love and be loved, and civilization is on the verge of collapse. The original will of the quantum cloud reveals: Only by picking off the core rose that binds the soul of "Su Wan" in all universes can a vaccine be created to save all things. Lin Shen was forced to pick off the rose, and the universe was saved, but Su Wan began to forget her lover, and the existence related to her was also erased.
Lin Shen, who collapsed, learned the cruel truth: Quantum Rose is a vaccine that needs to be fueled by the complete love memory of a pair of souls. And he, the remnant soul of Su Wan's lover in the previous crisis, was chosen to perform this new round of sacrifice. Unable to accept the rules, Lin Shen used the power of the broken rose petals to break into countless parallel universes to find the forgotten Su Wan. He witnessed countless times of her being confused due to empty memories, until he met Su Wan, a painter, in a main universe with a technological level similar to that of the Earth in the 21st century. She has not completely forgotten, but her memory is broken and the vague image of her lover is painted all over the canvas.
