I did not understand those last words from the emperor. Maybe I went cross eyed...someone help
Some clarification based on the exact dialogue within the novel: the emperor is saying that he loved the MC, and that he was 'blinded' by the MC as well because the MC was so bright. The MC thought (and still thinks) the (past) emperor was so cruel to MC because he hated him/wanted to humiliate the 5 families through him. And the emperor says to MC in the vein of: 'it was always about you, not anyone else, how come someone as smart as you didn't know that?'
Wow! Jihwa is some special kind of dumb ass...that is all.
