Try Refresh Man. It has the same male lead as Just You, and some people say it's better. I personally like Just You more, but you might like this one. The boss status a a little more emphasized.

Introverted Boss
Oh My Ghostess
Strong Woman Do Bong Soon

I agree with you, Boss and me indeed set the bar too high for a office Rom-Com. Since then, I've also been searching for something that will be comparable to Boss and Me.

These my not be comparable to boss and me, but must Try:

1. Refresh Man

2. strong girl bong soon (*)

3. Time teaches me to heal

4. About is love

5.  What's wrong with secretary kim (*)

6. Protect the boss

7. introverted boss/my shy boss

8. Suspicious partner

9. jealousy incarnate

10.  clean for now with passion

11. jugglers

12. oh my lady  (*)

13. well intended love

14. the fox's summer / fox fall in love (*)


I'll try to think of the other dram's that i've watched. I marked (*) those that i enjoyed most.
