You are Ga-yun Yuri, a not so typical high-school girl who is the 'lone wolf' of your year. You are most known for your cold personality, and your incomparable beauty. Yet this is just a facade, just a game you play, and only few can see through it. And those who see through it, are the ones that have captured your broken heart. Who will be the one to mend it?

No Minwoo, a guy who's heart was apparently 'stolen' by you. He had fallen for you. Not saying anything else, you both are tied in a relationship and tagged as boyfriend and girlfriend. He too wears a facade—only a facade that is much different to yours, and hides deeper emotions that have never been brought out by anyone before.

Ahn Daniel, a lively boy in your year, who finds his way to become closer to you. Besides your best friend, he is the only person that you feel comfortable with, comfortable enough that he sees through your facade. He seems popular, but really, is isolated from friendships. You have made it your duty to help him find a true friendship.

Lee Mi-yung, a girl with a bubbly personality, but shows a cold shoulder to you. Faking a sweet personality, both you and her share a bitter past that made her become so distant to you. She is the queenka of the school and is very popular, not only with the boys, but shares many friendships with girls too.

Jung Dae Hyun, your best friend's (Maria) older brother. One day, he suddenly demands to meet you through a text message and even enrolls to your school because of Maria's request. For a special reason that is unknown to you, he follows his orders to become your friend. You both share the exact same personality and unconciously understand each other.
