Architect Lin Shiheng accidentally entered the "Time Retrospective Correction Bureau" because he missed his crush on his childhood sweetheart Shen Qingxu in his previous life, traveling through time and space as an executor to make up for Shen Qingxu's regrets. From the dust on the jade button in the theater in Peiping, to the lingering warmth of notes on campus in the south, from the particle resonance of the interstellar space station to the mutual dependence of the piano and sword in the mountains and forests of Jiangnan, he struggled between rules and love, and finally rewrote his destiny in the real world, and stayed with Shen Qingxu across time and space.
Concept: Love that spans time and space can make up for all regrets
