Time travel plus butterfly effect plus a bit of suspense plus non-confined space loop plus BL!
Li Chengyue never imagined that he was just an ordinary office worker. On the subway to Zhujiang New Town today, the subway stopped and two people suddenly appeared. One of them looked very similar to him, or more precisely, exactly the same. He was said to be himself in another timeline. The purpose of coming here was to save himself in this timeline and prevent him from getting on the subway at 8:00! The other was a boy, but Li Chengyue didn't recognize him at all!
The boy also behaved very strangely and said he was his husband.
Os: I am also a boy!
——So this is a strange circle?
——Like an endless Möbius strip that keeps looping?
— Or an old tape that can be forwarded and rewinded?
——What will happen when the subway restarts? Or is this a key?
——It turns out that we have been together in many timelines!
Concept: First person perspective at first, then changed to normal perspective.
