Girls disguised as boys or mistaken for boys.
If you know of a title that's missing from this list (even if it's not found on MyDramaList) please let me know, and I'll add it!
Tawan Yor Saeng (2010 / Thailand) - I've seen a couple comments that this is a gender-bender, but none of the synopsis' I've found mention that at all. If anyone knows for sure, please let me know!
