I'll try, so basically huimin travels from the real world to the book, silence, whereas iheon travels from the book to the real world in which huimin, the one from the book had drawn/painted a story about them both.
The plot twist here is the "real world" is not the original timeline, and it is actually the drawings/paintings that book-huimin had drawn.This explains why the world revolves around huimin and time stopped working when he's not there as the "real world" is just a fragment of huimin imaginations.
In other words, the book is the reality and the "real world" is huimin paintings.
I don’t understand what’s happening at all. Someone please spoil me and explain the whole story??
