Choi Sooyoung the number 1 model of the ELite modeling company. She's seemingly smart, attractive, athletic and talented person, who appears to be the best model. Both her male and female peers express their admiration for her, often asking her for help and commenting about her model features and characteristics.  She act so perfect only to be admired, treated special, and pampered.  However, Her "perfect" exterior is merely a façade to hide the fact that everything she does is done solely to receive praise from others, and that she acts slovenly at home. She is a self-professed "queen of vanity", having been that way ever since childhood when her parents would praise her for the slightest actions. 

But one night Yuri a magical being that could conjure curses and spells with the power of the moon, want to get a revenge from her so she gave a curse. With a cursed kiss from Yuri, Sooyoung changes into a man in a snap.  She passes herself as Young Soo. With each passing day, every inch of Sooyoung starts to fade, physically and emotionally, and starts to develop real male characteristics. 

From Soo Young a girl to Young Soo a guy

How will Sooyoung survive...
