Reading, photography, learning, traveling, internet surfing and to name a few.
She has been making her presence in the industry steadily with JTBC's Be Melodramatic and the movie Secret Zoo.
She made her feature film debut in Park Chan-wook's film The Handmaiden 2016 where she was chosen from among 1,500 candidates who auditioned for the role.
I dont think she would say something like that if she actually was gay.
She is one of the popular actresses in the world of cinema.
Let me know in a comment.
