if you're into manhua go for "here u are", it's the classic college bl love but nice story telling and good pace. if you like a bit of fantasy go for "countdown to love", it's quite short but it has a unique premise and beautiful art. if you're okay with black and white go for "fools", it's old manhwa, it's a classic too, if you haven't read it yet give it a try. these three have green flag tops but all are not smut heavy.

Ive read pretty much all of the popular ones maybe some less known ones, preferably longer ones but all are fine, so is smut just maybe angst and such to a minimum, or just no very sad stuff like rape or things like that within the relationship
