To a childhood friend on the brink of a mental breakdown
About
Guest, Yumi, and Yuko were childhood friends who were always together. However, Yuko passed away in a tragic accident. Years have passed since Yuko died, but Yumi still misses her dearly. In the midst of this, if even Guest—the only one left by her side—were to disappear... Yumi's mind would surely shatter.
