[Slow-paced + Ensemble Cast Elements + Growth + No Cheats]

Ji Nian is an ordinary office worker, spending Monday to Friday repeating the same daily grind and sleeping in his dorm on weekends—a seven-day cycle that plays on endless repeat. Everything stays the same until a newly hired assistant disrupts this monotonous loop.

The assistant is a very beautiful girl. She takes him hiking up mountains, to see the sea, to amusement parks, and to do many things he’s never experienced before... But for some reason, even though these are all things he’s never done before, Ji Nian feels an inexplicable sense of familiarity—almost as if he’s done them not just once, but many times!

Until that day, when he’s driving alone through the silence...

Thick fog hangs over the airport, international flights are delayed, and an ace agent from the Space Survey Agency navigates a polar vortex. Enduring severe turbulence, his passport expires, and his luggage is lost, he finds his own body on the baggage carousel, clutching the pendant of his ex-girlfriend, whom he had just met thousands of miles away in New York City. On the tarmac, at the airport control tower, in the cockpit, in the first-class cabin, even on communications satellites... Mysteries unfold in every corner of the sky and on the ground. Who is behind this? Under the vast sky, when will the mystery lift?
