I feel like the author doesn't know how to make their relationship 'work' or maybe look 'better' after all what Caesar did. It's like a last pull of string to make the story work. But still it was poorly made when it comes to Leewon's character. In some chapters, especially his future conversation with Vladimir, he made more sense. But when it comes to Caesar, the author doesn't know how to make their interactions 'work' together. Because if Leewon made more sense, I doubt this story would still have any romance aspect and will end in tragedy. The author has plenty of room to make the dynamics better and make room for development, but the author took a short cut and dragged the side stories instead of a new season. But these are just my thoughts though.
Lee won is more frustrating to understand than Caesar.
Caesar is a bad guy, period. He's not pretending to be good nor showing any signs change and yet Lee won keep expecting him to be a quiet Disney prince. and the thing is, Caesar trusts Lee won's words and actions, that's why he goes batshit crazy whenever Lee won renege to his words nor actions, because for him, it's the finality of their relationship. His reactions are expected since he's a bad guy and he was raised differently.
Lee won, who was "supposedly" the emotionally intelligent one, keeps repudiating Caesar's whole fucking personality while claiming that he loves him regardless of his craziness.
Almost everything is in Lee won's POV and yet we still can't understand how he feels to the people around him especially to Caesar.
He always whine about how shitty his life there but didn't even think of coming back to korea, and maybe it's because he actually likes the thrill there but his words and actions fucking hurts.
