He admitted to Dojin that he loves him but still stubborn. I believe that the way he is. In my opinion, Dojin clearly understand Hyesung and he know Hyesung very well. As long as they're happy. I don't see the problem. They all care but just don't say it directly.
I really like Dojin. He's a great dad and really loves Heesung. If just Heesung could stop being so damn stubborn and admit to himself that he really loves Dojin. He's so bloody prideful. But ppl who say that he isn't a good parent seems to have missed his development as a parent. He really cares for his son.
