I think it would be Jung Yihyun…..he is atheletic, he has leadership skills and his body type in this would suit the general public females here in the US…….Unless you are into other cultures like KPOP and manga/anime fans, a lot of the general public females don’t seem to be into really skinny guys…..and unfortunately….Sikkie was really skinny before the military but then Happiness changed that dynamics. Sikkie as Jung Yihyun is bulked, but it’s the good amount of bulk too….really healthy looking. Sikkie is so handsome that any of his character would be popular here in the US but my personal pick is Jung Yihyun. I could see him in the boys basketball team, and boys baseball team….and I could also see him in student council and he would be like the president or something……
