Da-young Yoon is an elite in the secretarial world, has a smart job, and has a beautiful appearance. Perfection at work, with a thorough separation between public and private lives... Perfect in every aspect, she is forced to change her job due to her boss's scandal. That night. On the way home after part-time work, Da-yong, who is in trouble due to a drunken person, meets a man and who helps her. But that's not all, there are unexpected hugs, nosebleeds, and even kisses!

"Thank you, Boeun."
"Yeah?"
"Lips, nosebleeds, lifesavers. Isn't it something that can't be overlooked?"

Dayoung hands her flyer to a man who insists on her reward, saying it is her own business card, and she runs away. The man is her new boss, the president of the Koryo Hotel. Without even dreaming that it was Kang Do Hoon.

"Ah~ Was this the place you moved to? Not a knight"... Ruined. Is the dismissal confirmed from the first day? A sweet and bloody male romance between Da-young Yoon, and Kang Do-hoon, an arrogant man!
