Warning

Spoiler from Hugu:
Ml in the beginning he forgot that's why he acted like a jerk then he got his memories back in chp 25, the clue that ML has his memory was when MC said "Inheon" (cause MC calls ML as heon-hyung and calls his friend Inheon) and ML replied "your memories are back?" He was referring to MC's memories in the drawing book world. That's where he also realize that MC has his drawing book memories and doesn't have split-personality.

ML also realize that MC believes that the novel thingy isn't real so ML was playing along to keep MC's innocence and purity, he also didn't want mc to know that it was his real life cause if he does mc will leave him.

So there were 2 books, one book <silence> and the other one is a unfinished MC's drawing book (the non-omegaverse world)

They are the characters of the novel <silence> hence that book was their og life. So after all of the tragedy and abuse MC suffered what drove him to the corner the most was the death of his child lee seo.

after he had miscarriage he gave up on life and tried to unalive himself several times and ML groveling in regret ask what life mc wants he will make it come true, after that MC started to draw/paint again he was painting what life he wanted in his drawing book, a life not bound by fate, a life where ml is comfortable and a life where mc followed his mom instead of his father.


Fast forward, so ML's family and Villain's family made a pack that ML's family should not harm Villain's family. But ML didn't keep that pack cause Villain's family kidnapped MC which in middle of rescue ML got shot and died then MC also unalive himself.

Both of them died they transmigrated to MC's drawing book the non-omegaverse life, MC has no memories of novel silence but ML has his memories intact. so ML was stalking MC to the library and he stumbled on the novel <silence> which was exactly the same as their life and the characters are them too so he kept that book. Later he realize they were living in MC's drawing book cause only the area where mc is, will have color and have moving people if he leaves the people will turn into "puppets" and the area will loss it's color so pretty much everything is fake.

ML was also aware it's the drawing book cause he saw that drawing book and it's actually this drawing book that he wanted to get rid off when called his secretary to get something from Huimin's studio in chapter 27.

So for 7 yrs ML endured his longing to have relationship with MC and stayed friends in MC's fake ass world. He tried to confess several time but always there is something that will interfere it's like his only role is "friend" not beyond that.

So they were almost at the end of the drawing book which was in new years where MC will celebrate it with his mother, ML doesn't know what will happen after they reach the end of the drawing book so he asked Mc to spend it in overseas instead cause ML felt that if the book ends He will be erased, then MC refused to go to overseas that's where ML couldn't handle his bottled up obsession anymore, he told MC that he will twist his fate as long as he can have what he wants (mc)
"If your will can create heaven (the non-omegaverse life) my will is to create hell (going back to silence) with you"

So ML sneak the novel to MC's belongings in hope they could go back to their original timeline and he can have MC back.

That's how MC got in the novel.
As for the author of silence idk who that is, cause the last page was torn.

- How did MC found out the truth -

So after resolving every conflict In the novel MC knew, he finally accepted that he loved ML more than his previous world so he gave up going back to that world and have a child with ML, so they did snu snu to try get MC pregnant after a few months MC was having stomach cramps so he wanted to go to the hospital and see if he is pregnant. ML said no, he has to come with mc and MC was stubborn saying what do u not trust me (well something like that) their little fight eventually led to ML saying MC should stop his therapy session in which angered MC cause he felt that ML is belittling his efforts on trying to understand himself. So he went to ML's study to search for a book about amnesia or split personality he couldn't find any he speculate that ML was hiding them so he went to ML's safe and entered his birthday but the birthday that work was his birthday in the non-omegaverse world, so he was suspecious about the ML then he found his drawing book inside and the novel in ML's safe box. That's where MC realize that his friend and ML are the same person and that ML knew everything and he felt like a idiot being cozy in the prison ML created.
He ran away, he ask ml's grandfather chairman yoon to help him (he helped him cause he owe mc and mc looks like his dead lover)
then he went to the omega facility and found out he really is pregnant so he was happy his lee seo is back
