I just read the last and the first chapter and bro they were giving hints all the time. So iheon was first in the silence book, after he died he was sent to this alternate kind of world and became friends with huimin, whom had forgotten his previous life's memories (in silence) he also mentioned that while reading silence he felt like he lived what happened in the book (in the first chapter)
So in conclusion, they both lived the life in silence, they both were reincarnated into another world (huimin is without his memories) and both transmigrated again to the beginning of silence.
I did not expect that

A lot was going on in the little of 7 chapters,so I'm gonna list them:
Arranged marriage
Male futanari
Double d!ck (like top had 2 of them)
Double penetration (he used both of them at the same time)
Drug usage
Onahole connection (the toy was connected to the hole of the mc)
Exhibitionism (office and other one)
Bondage
Big d!ck
Mpreg (did not see the child but is implemented)
Wedding ceremony
Attempted NTR (mc tried to but failed)
And I think that is it ╮( ̄▽ ̄)╭

I think everybody feels this way but, I did not read nearly a hundred chapters, spent hours reading this thing thinking it was good (based in the ratings), and saw incest between a brother and sister. Like bro, I literally just took a moment of silence in the middle of the night and screamed in lower case (my family is sleeping rn).
So at first I thought he was a siscon, yk brother who loves his sister too much (not romantically), as mc described him I changed my conclusion to a fucking lunatic who enjoys to see his little sisters underwear while he "taught" her. Like bro stop it, after I realized that he was seeing her undergarments all this time while she was punished until the point her body developed scars it made me feel disgusted.
It gradually became worse as he spoke through chapters 94 to 95, and the worst thing stroke it.
I really want to fuck up his live, humiliate him, torture him, have him beg for his life and kill him
(=・ω・=)
This is just a theory guys
Maybe the second life of both mc's were just a wish of the original huimin. Like he wished that he would be friends with iheon, live without any omegaverse thing or something. That drawings are some kind of manifestation board fr
OOOHH COULD BE!!
