Lead girl is rude , blunt and says it how it is

Looking for a drama with a strong lead girl, someone whom people will call straightforward and rude , and with no manners...Someone who can be even stupid or annoying  sometimes xD

Thank you for reading ^^ 

Thank you Izzy  but I'm more at a misunderstood teenager vibe lol It's been a while since I last seen something like that,I think the last time I've seen it it was on the drama Doctors , and the charater quickly changed...I heard Cinderella's sister is not bad regarding that aswell :/ 
I haven't seen Long Vacation yet , but are you sure about the lead girl?
Also thank you once more :) eheh
