This Drama was amazing! I love the story line, it's not those typical time traveling dramas. You must watch it. I wouldn't watch it again but that's because I don't like re-watching a drama. If you haven't watched this drama you really should. The music really goes well with the Joseon era scenes.
You can watch this Drama on Youtube, Drama load, Ep drama & DramaFever (To watch it on Drama fever you must be a USA resident, I'm not so I couldn't watch it on there :p)

Total score : 100/100 It's really a good Drama ^^
