korean drama The Lover has also a couple that seems to be gay. They relationship started like bromance so it is possible that it is just queerbaiting and there might still be possibility of ending it like "hahah, just kidding, they are just friends!!1!!" (i havent finished it yet, but so far it seems like there are definitely some gay feelings)
i also heard about korean movie called One Night Only but havent seen it yet, so i'M not sure about its quality :)
