Su Nian guarded the second-hand bookstore on the verge of closing, and also guarded the hidden pain of being broken up by his first love Shen Yizhou three years ago. Until a cafe opened next door, the owner Lu Xingyan always approached her for various reasons - he remembered her preferences, helped her solve the rent problem, and used design drawings to outline the symbiotic space between the bookstore and the cafe.
This seemingly casual designer hides the past bond with her and Shen Yizhou. When Shen Yizhou returned with "compensation", Lu Xingyan's sketchbook, tin box for storing candy, and clumsy guardianship made Su Nian understand: what expired was not love, but unspoken regret.
Finally, the walls of the bookstore and cafe were opened, and the moonlight on the hanging chair illuminated the new agreement. Some heartbeats will be late, but they will not be absent, just like the new stories they wrote together, warming up all the old times.
