There is also To the Beautiful You. A korean drama, it's a romance comedy that involves sports. :> I think it's cute... and having Choi Minho(Minho from SHINee) is also a bonus x3
Ma Boy : Boys crossdressing as girls and its kinda good.
try IS - otoko demo onna demo nai sei...its not exactly gender bender, but it does have the same feeling to it, and is done really really well, so ull deffinitelly enjoy it...
In The Great Queen SeonDeok the main character pretends to be a guy for the first half of the show in order to hide from assasins and join the military.
I have finished whating ma boy its very sweet to the beautiful you is also recommended
i already saw the trailer too and i watched the whole thing;D
I have been watching two new dramas both are gender bender. The first one is Nail Shop Paris. The second one the girl dresses and acts like a boy and for the first 10 or so episodes the male lead believes shes a boy, its called Gu Family Book. Both of them are still ongoing but have been great so far.
