in the last part, yeon woo's existence almost vanished when he became the black king but he persist because of his family and friends. and he especially remembered edora i think he even sent her a personal message to wait for him or he'll be there soon if i'm not wrong. edora waited for a long time i don't know if he remembered yeon woo or not because all of the people who know yeon woo forgot about him when he is rewriting the myth of the black king except jeong woo who is in a library and doyle i think he continued being his apostle after all. so that's it yeon woo sent edora a message that he'll especially see her i think he liked her too sorry hahha my memory is not very clear
