I'm having the same confusion here. It might be two things. He kissed him goodbye which doesn't mean anything since he sees him as a brother or he kissed him and get married because he knows they can't be together because they are both man. I just hope it's the first one.
I believe he had romantic feelings but thought that they’ll both be better if he left. So that they could follow what is the next expected step. He probably felt guilty and that being the eldest he had encouraged biased feelings.
It's clearly not romantic, just a respectful goodbye kiss on the hand. As you can see, the man's head is positioned far from the prince's face, maintaining clear distance. There's absolutely nothing in the image or Manhwa that suggests or implies anything inappropriate from him, let alone pedophilia.
But, am I wrong or did Sam actually have some romantic feelings for the king, because he kissed him before he left him??
I mean we don't see the nature of the kiss but..
Also he goes on about wanting to be the sole important person in the kings life before leaving soooo.... am I the only one who thinks this? or came to this conclusion?
