Well to me he didnt really have a choice. Its more a trick of the mind to endure all of the hardship. Remember that the king told him his family was all dead and conveniently stayed by his side so he would have no one else.
I think Sam doesn't trully love him, he just never had a choice but to
Just like some victims of abuse have a hard time leaving their abuser and convince themselves that its "love".
Give Same time to heal, and I hope he will clearly see that he was abused and never loved the king
I wonder what will happen next...will they meet again years later (like a 10year time skip)? Will the king move on (I doubt it though) ? I can't foresee what will happen next at all ^^""
Wasn't it the king's brother who had the daughter? Or did I dream reading that? I’m still finding it a bit hard to grasp how Sam came to "love" the king after all the torture/rapes in the first few chapters, but nevermind (づ￣ ³￣)づ
