Let Jooan marinate

I just wanna say let's give Jooan some times for him to grow into a better character. I see the author obviously made his character flawed like how he has this narcissistic side and a self-centered bc it is part of his arc. Once he starts genuinely falling in love with Seojoon, I bet he will becomes the character that we are all will adore so much, his character development will be so good.
We see him and Seojoon has the opposite personality, that's why when Jooan start to really falling in love with Seojoon, he'll learn how to care about others and not just thinking about himself from Seojoon. Seojoon will be the reason for him to become a much better person
