Cross dresser

Jang Seo ya, a wealthy but cold-blooded woman, had gotten a call from the hospital notifying her that her twin brother had been in an accident. “In the meantime, please act like me and look after my CEO,” her brother said before losing consciousness. Seo ya was taken aback by his remarks since he's asking her to work as a secretary for her brother's CEO, which is a homophobic—the type of person she hates the most. While investigating her twin brother's accident, Jang Seo ya tries to figure out what she did to turn a cold-blooded homophobic CEO into a gay who is head over heels for her. A homophobic and a LGBTQ supporter, what type of romance awaits them?
