Lee Ji Eun, a girl nicknamed as IU in her class. She’s smart, beautiful, and pretty much the girl you will like in your first meeting. She’s taking up the course of Architecture with ease because of her hard work in studying. She may got the looks and the brains but the only thing that she lacks is money.

Her Parents died in an early age because of an accident. Yet, It didn’t stopped IU in reaching her dreams. Her Mother’s sister adopted her and tried to raise her as a fine young girl.

She got accepted in a famous school because of a scholarship and because of those extra credits that she earned in her high school life. She has plenty of friends in her class and it seems that she has no problems in life with those smiles and giggles;  that you always stays in her face.

But they wrong. She has a problem that is stuck somewhere in her mind…. And heart??
