Lee Jiyeon, a nineteen year old girl who grew up in a little house in Seoul with her older brother, Mingyu. Their parents died when Jiyeon was only 12 years old. Their parents’ death was due to a car accident; as a result, they were left with nothing.. nothing but bad memories as they grew up moving from one house to another. Mingyu always dreamt of going to “Gangnam Private School”, an all-boys school and is the most prestigious school in Korea. He applied for a scholarship and luckily, Mingyu got accepted. The both of them thought that this was IT… until one night, in a dark area, all of his dreams were shattered by a certain event that the both of them did not expect.
 

Because of this certain event, Jiyeon had to change everything about herself. Changed her style, changed her looks, changed her image and changed her name. She promised to her brother that she will pursue his dreams and make a name for him.

From girly Lee Jiyeon, she became a strong, cold-hearted and brave tomboy-ish, Lee Mingyu. Everything was going well as she planned until she met the flowerboys of the school aka her roommates, Infinite. Will Jiyeon be able to keep her secret and fulfill her brother’s dream or will Infinite get in the way of her plans? Will Jiyeon be able to control her feelings for them or will she let it overpower her?
