TOP 5 Best Actress Playing a Male Roles....
1. Yoon Eun Hye ( K-pop girl group memeber, Baby Vox) - Coffee Prince 1st Shop, 2007
She cut her long hair and cleared her thick makeup, and turned into a young man. The girl group image is erased and the wicked 'Yabang' is displayed. The drama is still in 'life' of Yoon Eun-hye. The drama was become mega success. This drama was first leading mail role for Goo Yoo as well.
2. Park Min Young - Sungkyunkwan Scandal, 2010
She also has an unforgettable character for a male character. She was mixed with a male-female and became the center of diverse relations. It was the birth of the new genre of youth romance historical drama. Her look as a male and her performance are amazing!!!
3. Kim Yoo Jung - Love in the Moonlight, 2016
The drama is similar to the 'Sungkyunkwan scandal', her performance and her mail look are also impressive. Kim Yoo Jung shows a character of a male and female who can enjoy a sweet and cheerful appearance.
4. Ha Ji Won- Empress Ki , 2013-2014
This drama is about a woman (acting as man) from Goryeo marries Emperor Huizong (Ji Chang Wook) and becomes a powerful Empress of the Yuan Empire, Empress Ki. I think she plays beautifully and her action acting is great. I think she plays really well with any girl crush characters.
5. Park Shin Hye - You're very handsome, 2009
It's a drama about a girl who happens to be a member of the idol band taking on the role of gominam as a young man. Well I can tell she was playing a male character while hiding a woman, but I thought she plays very well and so cute with her short hair..
