All Krystal wanted to do this summer was to exercise by dancing so she enrolled herself in a dance school to learn hip hop (for a change since she already knew ballet) but things got complicated when her older sister's boyfriend, Donghae, started to like her and also, Donghae's bestfriend, Eunhyuk, liked her as well.

Jessica gave piece by piece of her heart to the men she loved in her life but what happens when one man was willing to give his entire heart to Jessica but she has nothing left of her heart to give to him?   Someone has to gather Jessica's pieces of heart but which one of the men would do it? Or would Jessica do it herself?

Jessica doesn't want Amber to keep on hanging out with Krystal.   Warning:  Yuri~! Girlxgirl.
