Although moon river doesn't have gender bender, the main lead girl is a tom boy and very innocent but is really good in martial arts. (love that fact). Oh and there is a love triangle which gives a very similar feeling to you're beautiful. Moon river is a taiwanese drama which got me hooked up after a long time (while taking a break from my usual korean dramas). Worth trying.

Well, aside from the fact that the lead role is played by Kang Ji Hwan in both the dramas, both of these dramas give off a similar feeling and has a lot of suspense to keep you hooked up and wanting to know what happens next. Worth watching.
