Some people would read a manga or manhwa for 3 volumes/seasons and still call the characters "seme" and "uke"
Does it just give me the ick because I'm a gay man? I know most people don't speak Korean or Japanese here but why is it SO hard to learn the names instead of referring to characters as "the one who shoves it up the ass and the one who gets his ass pounded"?
