Han Seo Yeon (Ji-Yeon) is a bright, healthy, and outgoing high school student who dreams of becoming a model, but she's worried about being rejected due to her height.

She then applies to a fashion show, in which Jin-wook (Kang Dong-ho), who is one of the top male models in Korea, is part of the approval board.

When Han Seo Yeon and Jin-wook meet each other at the fashion model show's casting, Jin-wook harshly treats Seo Yeon because he thinks she's too short for a model, and he doesn't want to deceive her by allowing her to pass at the casting, only to be eliminated from the show at a later point for entertainment purposes, and she leaves the audition disappointed.

Then, to cheer her up, her childhood friend Na-rae (Kisum) takes her to a karaoke bar to lift up her spirits.

In a strange coincidence, Jin-wook, who got fired from the fashion show's approval board, is also in the bar celebrating his friend's birthday, then later an incident occurs where Jin-wook and Seo Yeon switch bodies after being electrocuted during a storm.
