YESS !!! THIS IS EXACTLY WHAT IM THINKING
Spoiler:
I also copy pasted from another person, if u don’t want to know pls don’t read further
Basically uke's "real" world is fake. The "fcitional" world is real. So technically the stiry now is their 3rd life.
1st being = uke being sold and being raped and mistreated by seme and them dying. (Alpha and omega)
2nd = uke living his ideal life where everything is peaceful and the seme also was "reincarnated" or "transported" to the ideal world of uke. Here they were best friends because seme regrets everything he did to uke in their previous lives. (Normal)
3rd= uke trasports back to real world so does seme (alpha and omega world) but uke thinks that the real world was his ideal world.
I have a theory where like they both regressed and actually both of them are the real iheom and humuin and not from the novel silence and to like keep huimin beside iheons side he just pretended to be like in the novel cause what if in their previous lives iheon read silencd too its just that huimin didn't know cause iheon went abroad.
