Dating expert vs noob

Any drama where one of the leads is a "dating expert" and has dated a lot of similar "dating experts" and thus is familiar with whatever dating rules and then meets someone who's never dated before and there's hilarious misunderstandings because of this. 

LOL, I read a webnovel not to long ago where the FL seemed to know all the stuff around dating and I was like: I'd be KO the first word that came out of my mouthand remain single for the rest of my life if everyone followed these idiotic ideas.
