My name is Kim Eunji. I have one goal in life, and that one goal is to make him regret.

Kim Eunji wasn't a pretty girl. Every guy she liked always rejected her, she was always left out because she wasn't like the rest. She wasn't loved because she wasn't like the others. It was because she was fat. While at a talent show, her guy friend started being close to her. Flirting, touching, be cute and all. She slowly likes this guy more and more, but because she knew she'd be blown away, she set a plan to get skinny. But her plan fails after many months. In the end she was rejected again. After being depressed for many years, she finally pulled off all the weight, and he tries to holla at her, while dating another girl. She no longers feel anything for him, and she is detemined to make him suffer, and regret loosing her.
