• Search: WWW - ML is CEO of a small company that he started. The FL is an executive director at a big company.
•  The Master's Sun - ML is a CEO. FL is not a business person but isn't "normal" in the sense that she can see ghosts. The leads were a bit difficult to like.
  
• Strong Woman Do Bong Soon - ML is a CEO. FL is not a business person but isn't "normal" in the sense that she has super physical strength. I found the leads childish and ended up dropping this drama.

I know this might be much too late. But try 

Gosh, The Stary Nigh - boss in love with subordinate for a while.  Subordinate ex comes to work with them.

Refresh Man - boss and subordinate used to be childhood friends, where the roles were reversed.  I promise you the ending is truly good.

Perfect Match - boss and subordinate challenge each other to cook off.  You'll learn about different flavors of curry.  No joking, the different ones are interesting to me.

Lastly: Me Always You - Thai's version of She Was Pretty. That show touched Mt heart more than SWP.  

Hope I helped
