Overworked commercial Assistant director Choi Bo Na is an average girl lacking in social sterminates, self-confidence, and romance. One day, after a long day of shooting on the beach, she comes across a travelling book and movie stand selling a VHS tape titled “Male Instruction Manual”, promising to help her move up in the world by using the very same people who dominate it: males. Despite being skeptical of the video, shelets herself be coached by the video. She soon finds herself sought after by men including tacky top star Lee Seung Jae. In their on-and-off relationship, they never seem to be on the same page romantically. The same tape that caused Bo Na’s success is the same thing that drives a wedge between her and Seung Jae.
