I doubt he like him only for his looks, just like Hajin don't like his bf only for his good looking looks. I think it's deeper then that. and he sew how he suffer by being kind, I think his love is much deeper then just a "challenge" pase.
and the same I can say about Hajin, he still a selfish brat and didn't stop been a selfish brat that start to cry once things don't go his way.
I'm dying for sungjoon and Taehyun to be together, for Taehyun to learn to be a little more open about his feelings and be a little more selfish just like Hajin is. and to be more spoil. for that he need Sungjoon to fill his void cause everyone else seemed to ignore him. and Sungjoon isn't that bad, he is playful and easy going, open and honest and a little selfish at times. but he know who he love and he will follow him.
I’m not sure why but I still dislike sungjoon and have from the very beginning. I really haven’t clicked with him. I feel like he only like taehyun because he was good looking and now is after him because he can’t get what he wants or he wants some sort of challenge. I really don’t want sungjoon and Taehyun to end up together.
