Koki Yamato, a popular high school junior, believes his life is relatively normal. He gets decent grades, is the heir to an enormous family fortune, is a star athlete, and is recognized as the school idol. However, one morning when he meets a boy named Chitose Fuyuki, who claims to be his childhood friend, his whole world is turned upside down. Koki comes to realize that he's lost parts of his memory. The only parts he's lost, however, are those related to Chitose. A startling revelation indicates that Koki and Chitose's relationship with one another ran much deeper than a simple "friendship". How will Koki deal with the struggles ahead? Chitose's life hadn't been easy. As a child, he had been teased for his girlish appearance and shy nature. His parent's social status and wealth only set him farther apart from other children. The only person he was truly close to was Koki Yamato. The pair had been inseparable since birth, and they knew each other better than anyone else. However, when Chitose loses his parents and is sent to Hokkaido to live with his reclusive grandmother, he is torn away from his dearest friend. After two years without contact, Chitose returns to his home town. However, his reunion with Koki is anything but the warm welcome he had always imagined. In fact, Koki can't seem to remember him at all! Chitose must find a way to accept this turn of events and overcome the challenges of his own loneliness. What will come of their forgotten childhood promise?
