[Everyone, just start reading from the third world, Chapter 19: Someone Else's Husband A and Someone Else's Wife O. The first two worldlines are unclear.] Note: Both leads are completely devoted to each other.
Gu Yian thought he was an innocent Host who had died young, while HH thought he was a System with no roots or home.
A System binding itself to a Host to complete missions is only natural. But reincarnation means your soul travels to another body, and being reborn means starting over in the womb. You can never escape cause and effect.
The mystery has been set in motion. In one world after another, the truth is right before them. What choices will they make?
[The plot is angsty, but the relationship isn't. The first world is full of mysteries. Get ready for an exciting story.]
