Looking for k-drama where the lead girl is the guy's superior, whether it's boss x employee or more like master x student(as in teaching the guy how to fight, survive in the criminal world, about business, making money, or similar. I'm not looking for teacher x student in a school setting).

Stuff that I've seen that fits: 

I Do, I Do - girl is team leader, guy is trainee. She teaches him about designing shoes.

Big Man - sort of: Guy is clueless about business, the girl helps him out.


Thanks! :D
Ugly Alert- He works for her throughout the series.
