Wen Yidu, an agent who carries out missions across time and space, has a secret task he cannot tell anyone about: he isn't here to win over the worlds. He's looking for someone.
Ten thousand years ago, his beloved, Shen Qianchen, sacrificed himself to save Wen Yidu from the turbulence of time and space. His soul was scattered, and he fell into endless cycles of reincarnation. The laws of the universe erased his memories, making each new life a fresh start, with no recollection of the past. Everyone tells Wen Yidu the same thing: He's forgotten you. You'll never find him.
Wen Yidu refuses to give up. He binds himself to a mission System and travels across three thousand worlds.
He has seen Shen Qianchen take countless forms in his successive lives: a cold Demon Lord, an innocent scholar, a sinister villain, a gentle moonlight beloved... Each time, Wen Yidu has to approach him anew, get to know him again, and make him fall in love all over again.
He's long since grown used to the cycle.
Until, on this mission, he disguises himself and enters a small world. As he passes a flower stall on a street corner, the florist suddenly looks up.
That gaze is exactly the same as it was ten thousand years ago.
The moment he sees Wen Yidu, tears spill uncontrollably from his eyes.
He doesn't remember. But his instincts have remembered for ten thousand years.
Later, Shen Qianchen asks him, “You said I used to be very clever, so there's something I can't figure out. If I could recognize you at a glance, why did it take you so long to find me?”
Wen Yidu falls silent for a long time before answering softly, “Because before this, you never once looked back at me.”
“And this time?”
“The first moment you looked back, you recognized me.”
Time and space are paper, reincarnation my pen. I wandered for ten thousand years, wagering everything on one glance back from you.
