I'd eat his pussy like it's my last meal. I'd salvage the taste, I'd make sure he's left shaking and twitching. I want my mouth to be soaked in his liquids. Once I get my hands on him neither of us will be the same. I actually need to get him pregnant, it's not a want anymore, it's a need. I'll bend him over and make him see stars. I'll take him to heaven myself, I'll make him forget about wanting to go back home. By the time we're done the room will be torn to shreds, the walls won't survive the fucking I'm going to give this man. I'll make sure his body remembers me for the rest of his life.

So Soho is some sort of "monster" capable of memory manipulation and he also can cause either illusion or copy voices (maybe both?).
I'm guessing the only why he can "grow" is by either manipulating memories or more physical actions with Russ.
Honestly I'm sceptical about Soho actually being Kaya's son, but he definitely has some sort of tight connection to her. It seems like Russ has trauma and PTSD from something but Soho or someone else keeps erasing his memories whenever he has a PTSD attack. I'm guessing this trauma also has something to do with Kaya.
Honestly I'm just as confused as everyone else

Honestly the author really cooked by showing us his father through his memories cause tell me why there's a part of me that still recalls those panels where his dad actually seemed like a good dad. Even if they were vague
It's easier to hate a character that has been only shown in a bad light, but Wonwoo still remembers the dad he used to be and that's something that makes it feel a little more real with how easily Wonwoo gives into his dad's wants earlier in the series.
First Manhwa to not have obnoxious favouritism towards the MC
I've been waiting for a Manhwa where the dad (specifically the dad) doesn't neglect everyone but MC and where the mom isn't dead for no reason
I KNOW RIGHTTT, THIS IS SO WHOLESOME I'M SO GLAD THE AUTHOR IS NOT BIASED
The mom is badass too
