Well the fact that he didnt get rid of all the other princesses and his family intends to replace the queen, I definitely do not root for the black haired guy. I always feel bitter whenever he is in the screen with her. I really expected something from him, but after 70+ chapters, i have only been dissapointed.
I thought that was done behind his back. His father overstep and accepted a deal with the b♤♤♤♤ princess' family
The fact that she was alive and the father helped her escape was behind his back, everything else he knows. The only thing he doesn’t know, nor do we know, is what his brother is going to do behind his back. I would say he doesn’t know Hong’s plan, but he definitely suspects that she is going to against him.
Don't get me wrong, this story is very captivating and interesting, but the tension and not knowing who she's gonna end up with makes me really anxious, so I'll wait until it's done to finish reading it (・_・;)
