They say; Reassurance is a love language for people healing from Trauma.
How true is that?
Like I said before, Seo-Jun wanted some sort of validation to know that what he's doing is okay even if he knows that it might not be okay.
And since the people he was always with were those who wanted to use his influence and wealth to get big, he always got that validation... Even though they were all lies.
I'm sure he knew it but his ego did not allow him to see the truth. Just like how humans only chose to believe whatever they wanted to believe, Seo-Jun believed all the lies and filtered out the truth, honing his arrogant and 'I-don't-give-a-fuck' attitude.
He couldn't care less about how the world worked and focused on how it worked for him.
That was how he had been living his debauchery life this far.
But of course, he wasn't stupid either so he never actually fell for the trap of those who wanted to bring him down.
He just lived... A certain way.
