It all started...with a piece of trash. -- Morinaga Ayaka passed her two years of high school at the prestigious Tennouji Academy with no fuss. Now on her third year, she was quite certain it'd pass the same way her past years did. Unfortunately, however, she was proven quite wrong. Being a transferee, she didn't bother to get herself properly acquainted with her new school's students. This proves to be a fault -- especially when she unknowingly starts a spark between her and Tennouji Academy's elite: Amamiya Takehiro, heir to the Amamiya Group. Little did she know that meeting him would bring back the past she had tried to leave behind. All of this, and it started only with a piece of trash.
