Recap anime: It has been 7 years since the death of his older sister, Kakeru still can't get over the shock and always shuns the world around him. Fortunately, he always had a childhood friend named Yuka, who stayed by his side, and took care of him during that difficult time. Yuka and the two Kakeru sisters have been close since they were in the orphanage. Even when Yuka was adopted by a family, their relationship did not change. In addition to his childhood friend Yuka, Kakeru has two other friends, Tadashi and Kaori, who make him feel at ease whenever he's around them.
