I don't think they're brothers guys, yk in Korean culture boys call their older male friend hyung etc but if they rlly are then this has officially ruined the manhwa
traditional romance (with a mix of modern ofc) is some of my favorite and I've got to say, no one does it better than the ghosts nocturne. truly my favorite for a reason.
jaeshin is adorable but plsss communicate its driving me crazy
