I’m worried of what you have said. If nakyum has become yoon’s weakness, i bet people is going to harm nakyum ma baby. Yoon got so many enemies, they will harm nakyum for revenge

He is intrigued by NaKyum. Since the beginning, The boy kept antagonizing him and Seungho kind of likes his courage. He likes also his expressions, those always trigger something in him.
Even after slapping NK because of the damaged painting, he knew for sure that something was off and didn't go further with the punishment.
Concerning the assault, he knew all along that NK was excited and for the first time in his life, his 'little son' reacted by itself.
I just realize yoon only be gentle when it comes to nakyum. Aside ch.1, even how angry he was he nver pull nakyum’s hair like he alwys did to everyone else.he only grab his neck or back of head, so it won’t hurt nakyum. He hits or kills ppl as he pleased but when nakyum got a cut on his lips bcoz of his light slap, he worried much. He will kill ppl who badmouth or lies to him but when nakyum badmouth him call him “lust man won’t understand” he was smiling..? His personality gap is something i love bout him.
