Donghae and Eunhyuk had been best friends for as long as either of them could remember. They lived right next door to each other and would spend almost every waking second of every day together. Even when one or the other had to go home, their bedroom windows faced each other and they would spend hours talking to each other about whatever pointless things came to mind. From kindergarten all the way through their freshman year at high school they were inseparable. But then, the summer before their sophomore year, something happened that threatened to year the two best friends apart forever.
