Something similar to Ha Kyung and Nam Soon (which is sadly never happened) from School 2013 or Eungi and Maru from Innocent Man. The female lead must be proud, confident, a little bully, and full of herself. The failed versions of 'arrogant' female lead would be Take Care of The Young Lady and Couple or Trouble where the female leads don't even have any common sense, let alone brain, to back up their aggressive personality, which make them simply unlikable and unrelatable. And what I mean by 'quiet' male lead: doesn't talk much, every words that come from his mouth is direct and effective, rarely fail to keeps his cool, looks 'nice' and harmless all the time yet no one ever knows what he's actually thinking and what he's capable off.
Thank you :D.
