clearly you did not read the story well and ignored takus whole development and character. he had a development like joowon did. they both became more mature and taku learned how to love haesoo.
Taki definitely started to feel emotions and fell for the first time but his reaction for example during break up isn't the most mature one.
development doesn’t have to be positive tho,, he’s showing more emotion/reactions that he wasn’t aware off and thats why he can’t act mature,, maybe just like jowoon and haesoo acted at first
Oh in this sense he definitely had character development. But the other reader compared Taku's development to Joowon's and imo they are a little bit different. Because it's not your decision to start feeling emotions, it was out of Taku's hands. On the other hand Joowon's development was him reflecting on his actions and trying to be and act like a better man.
i really like how Taku's character is portrayed and his development in the story ,,,,,,, but it still hurts i like so much dfjkglkñ
