Bae Joohyun is an absolute alpha bossy woman who always does things independently and has anything anyone ever wants in life; wealth, power, position, influence, nobility, etc. She is the real definition of a woman who works wonders and phenomenal things that cause other women to look at her with envy. She is blessed with great luck in everything she does, no matter what time and where is the place. That is until she meets Kang Seulgi who never fails to transform her supposedly good day into the worst nightmare ever; spilling coffee over her white blouse, stepping on her shoelace that her wrist is wrapped in a cast, and lastly forcing her to fall in love with Seulgi when she never has any plan to.
