It was hard to make a title for this but Mask was the only drama I could think of which does this. Can anyone recommend a drama where the main character gets sick of being pushed around, does a 180 turnaround, goes 'Stuff this I'm badass." and then proceed to take control of their life and acts revenge upon all who wronged them? Kinda like the main female lead does in Mask. Thanks :)
