Brothers Hideyuki and Hideomi Togame have a private family rule: A kiss for sadness, a hug for happiness, and for loneliness, they share their body heat. The two have been living alone together since an unfortunate accident left Hideyuki with anterograde amnesia - much to the disappointment of his parents' high expectations for his future - and Hideomi has taken care of him ever since. But Hideyuki's dependence on his younger sibling coupled with Hideomi's possessiveness has created a relationship more akin to lovers than brothers. What does the future hold for their strange relationship?
