Hi

It is a story of Choi Young-do and Kim Areum, Kim Tan's twin sister. They used to secretly like each other as kids but when Young Do and Tan had a falling out, their unrequited love remained like that. Soon the twins moved away to the States. Year later they are back and Areum thinks that all the feelings she had for him no longer exist. In fact she thinks she hates him because of how badly he treated her and her brother's Eun Sang. But is it really true or she still likes him?
