What i don't understand is why both of them have different memories from the real life , like from POV of the MC his real life is hell , but from ML POV is like all good and smiles. Does he not know what has been going on in the house with the MC .

I think it’s matter of perspective, MC narrates his life while which was what he viewed as whole. While ML’s POV focuses on traits he likes about mc, cutesy act etc… that’s why it looks happy because it didn’t include what mc was going through.
There is also ML’s mother who isn’t favor of MC she probably said shit to mc which made him distant

No wonder Jiheon is over obsessed with Wooju , hes basically all he had from kids. The mom manager ( who i still believe is professor Cha father) just pick him up whenever he have time and gives him whatever junk he have time for to eat.
I have a wild guess that the manager is not even allowing to his mom to call him "because she need to focus on her career and not her own child" , she may actually care for him , but hes like the middle men between them all this years. I won't be surprised if he tell her Jiheon haven't called her once.

Wait .... could it be hes doing it because of Jiheon mom too ?!!! Like he say before he accepted the house request because he know her. And when he first saw the picture of Wooju and Jiheon he was looking at him and said "Is it time" so when ever the heck hes doing hes been planning it from long time.
I secretly hope that secretary guy to have something with the kidnapping too , and he to get what he deserve not just from ML but his family as well as one big traitor all this time , because i think that why he hates the MC so much , he think he member him from back then , not because he was there when it happened.
