This really should have been episode 21 of Dr. Romantic as the events take place after Episode 20, and two big things happen. The hospital's rumor mill goes on overdrive as soon as 2 letters arrive. The overseas letter is for Doctor Kang, and he begins to act all mysterious about it. And then a mysterious lady turns up at Doldam Hospital - she's come there to ask Master Kim to treat her very sick work colleague, as they have a past history.

If you enjoyed Dr. Romantic, you'll enjoy this. It shows some additional character growth, and reveals quite a bit about Master Kim's past. I loved it and want to see more! Season 2, please!
