The parents is suspicious

Whats the theory
??

Sorry for the late reply.

It's a theory in the comment section (page:17 right now) by Someoneyoudunno (titled: based on the theories in the comments)

I quote;
[The mc probably stole Soobin's luck. The 1st chapter literally starts with mc thinking to himself how lucky he is despite not having any special talents. Only having a decent face and a rich family makes his life so smooth-sailing! That grandma most probably is a shaman and she probably knew what mc's future was going to be like so she must have made a luck stealing ring that stole soobin's luck (since he was the only kid around the same age as mc). Mc probably wasn't as lucky before meeting soobin and that's why his family didn't let him leave his house to keep him away from harm. If you know you know, mc's only friend in childhood was soobin and after meeting him, mc started to steal his luck (even though he didn't know anything about it). Soobin probably had a suspicion regarding this matter because his life suddenly turned to hell after meeting mc and maybe that's the reason why Soobin yelled "My life turned to hell after meeting you".
After done stealing his luck their family moved away from that poor neighborhood (which makes you wonder, if they're so rich then why would they even come live here? Probably because for them poor person is more easy to use...) and after transmigrating, his ring was already used so maybe that's the reason why in this life, he's not as lucky as his previous life (that is the reason why he keeps on saying "This never happened to me before, I was always so lucky") ]

Now that makes sense. Probably why MC realised that he started becoming as unlucky as Soobin (his actual luck) yet has no idea since his parents used him as a tool to get rich in return for all the money. That's why he was spoilt to the point of being able to do anything. Soobin, by killing the MC WITH HIS OWN HANDS, has cojoined his fate. Also why the lucky ring disappeared and whatever wounds or bad luck Soobin faced would also transfer to him. If only MC could ASK the FrekkinG Reason to his mom Why, he would have known.
Also, MC is really, like really slow to understand that his Grandma had foretold him of a shorter lifespan when he was young. Probably thought it was nothing and dismissed it, but EVEN Now, he doesn't know that he was destined to die young.
Definitely a boy born with a crow's mouth. Of course, it was the very same mouth which saved his life at times, but he honestly REEKS of Ignorance. Also, the reason why he doesn't care anymore is Only because HIS Life is in danger, some comments did mention ADHD, still doesn't give someone a reason to hurt others. He isn't completely apathetic, just wasn't taught properly to mind himself. A shame, he has to pay now for something He Believes He didn't do, imagine the time when Woori comes to know about it somehow through a chat.... waiting for his expressions to crack. Sure, he has changed, quite a lot, yet a long way to go.
What would be the sister's reaction IF she ever knew Her "Prince Charming" was the one to take everything Away from her and family Even though he didn't mean it?? Would she try killing him or do something worse than Soobin?
