Choi Bo-na (Lee Si-young) is a woman who couldn't be more ordinary. Not only does she look ordinary, but her personality is also unremarkable. Whenever her friends mention her, they only say that she is a "nice person" and nothing else. Such a Choi Bo-na naturally has no chance of romantic love. What's worse is that, let alone love, Choi Bo-na has very little experience in getting along with the opposite sex. Can she really find her ideal husband? By chance, Choi Bo-na picked up a "Man's Manual" on the set. Referring to the methods taught in the videotape attached to the book, Choi Bo-na actually began to become different from before, and even unexpectedly attracted the attention of the popular star Lee Sung-jae (Oh Jung-se). Does this manual really have magical powers?
