I'm not crazy about the artist's art style in general--particularly with how they draw glutes--but I don't think Seokjun's face looks bad in comparison to anyone else's, though his eyes are drawn facing downward (whereas Chani Chani's are drawn with the ends facing upward), making Seokjun look permanently sad, tired, or crazy, so maybe that's why you don't like it? Plus I'm not crazy about how small the pupils are; I don't want them to be as huge as a stereotypical uke in a traditional yaoi work, but the eyes are way too small and makes everyone look kinda villainous.

Chani chani is right, suck jun is so ugly. It’s not even an art style thing he just is so ugly and I’m not even judgmental most times. I have to cover suck jun’s face during smut scenes just to get turned on
