I think Eunyung doesn't even want his parents to want him back (well kinda) or to start 'liking' him, i think he wants to rub in their face the fact that by treating him unwell, they missed out on something great; he's rich ! He's successful ! Although at the same time he probably wants some sort of validation, but at this point he knows that's pretty much hopeless.
But that's not gonna make him feel better, that's a short sighted 'vengeance' that will just confirm even more how little his parents cares about him. Honestly I just hope he goes no contact as soon as possiblle
