Hye Jin, Hee Kyung, and Han Hee who are among the high school alumni. They met at the alumni meeting and heard that the male alumni who did not have a chance to study during their school days were greatly successful as an investment company.

Since then, Zhengzhou has been enjoying the love of female alumni.

Mi-jung wakes up a different gender every morning. She's Nam Mi-jung when she's a man and Yeo Mi-jung when she's a woman. Her friend Jin-soo is in love with Yeo Mi-jung. She also has a girlfriend named Eun-seo. A ridiculous love story takes place between these four people.
