he has a lisp, but a lot of Koreans do. his lisp is super cute
no, it's just an assumption. or it could be that he pronounces some words that way? whatever it is though, I find it cute too. it could be an accent too, instead of a lisp. might have to do some research on it
since you mentioned j-dramas, can you recommend me a couple good ones? I love rom-coms!
