Well I was curious and read the novel, webtoon version is written poorly, you can't feel the anger and desperate that Grand Duke and others showed when looking for their king as well as the great physical pain the king had to bear when his wing grew one more time and the struggle, mental pain of Grand duke when he must hurt his king to fix his bone.
I felt bad for the king he's like one of the most pathetic character I knew of... Author really doesn't miss a chance to torture him in all ways possible LOL
