i just gotta say tho, i have a feeling that the prince has feelings for seonwoo bit didn't know about it yet because he was busy obsessing about seonwoo and geumhoo's relationship
'coz come to think of it, when seonwoo decided to settle down with the princess, he sought to end geumhoo because "apparently" he had no use of him anymore.
and in the flashbacks he said himself that he likes how seonwoo looks at geumhoo so it's either he longs for someone to look at him like that (y'know that lovestruck look) or he loves seeing seonwoo looks in love and happy with someone (w/ch unfortunately only happens when he looks at geumhoo)
been taking my time to read this one because of the spoilers but it's so so so worth it
i love the beom and geum hoo, they deserve all the love
