I only saw two dramas from your PTW list but they're geat so I would recommend them anyway : - Coffee Prince : a classic for gender-bender fans, one good point s that the girl can really look like a boy with her hairstyle and voice in this drama. - The Moon that Embraces the Sun : very beautiful romance set in a period drama. No gender-bender in that one but the princess pretends to be a shaman.
For recommandation on my PTW list, please max 3 ^^
