i mean... i think haesoo had quite good development as well. like he admitted he was selfish and immature in how treated joowon, and that joowon wasn't the only one to blame. he also admitted he was in the wrong for wanting jw to fail or be set back in his career. plus him running to the hospital to confess to joowon: his biggest moment of development, where he finally decides to stop running away from his feelings and take control of his own life. he stops letting his mother guilt trip him forever and lets go of his fears or pride to tell his true feelings to joowon. not to mention, him choosing to take time away from a relationship for his own self growth shows greater emotional maturity too.
i can agree that joowon's development was definitely the best out of the 3 though
RIGHT? RIGHT????? As OP said and the person after it, both of these have had such wonderful character development. It's like they're real people, dude, I am SO imvested lol.
it’s the way joowon is the only character who’s had such good development. His redemption arc was so impressive, He went from being afraid of all the problems that come his way to dealing with them, head first. It’s the way he’s said to haesoo, no matter what, he’ll always be there for him. it’s the way he’s dealing with his problems and addressing them rather than ignoring it. I love him so much
