Daichi and Sugawara have been together since Kindergarten. In High School, Daichi and Suga find that the love they share for each other is greater than friends. They end up living happily ever after in an apartment they share in Tokyo, Japan. Or so they thought, but Daichi finds another, and ends up leaving Sugawara with no notice for weeks. Until a couple of months later of waiting, Suga realizes he is all alone. He spends a month holed up in that same apartment that he used to share with his lover. That same apartment filled with memories of only Daichi.
