It was the final winter of his school years, and with entrance exams and graduation drawing near, Nozomu was at a loss. He had been told to become independent, yet he could not find a suitable place to live on his own. His childhood friend Shiori could not bear to watch him in his current state and suggested that he move in with her. Although he felt it would not truly make him independent, his parents readily agreed to the arrangement. Before he realized it, they were living together under the same roof. Their cohabitation was intended to last only one month. Since it was merely for a short period and she was his childhood friend, he assumed nothing untoward would occur. However, living with Shiori revealed a side of her he had not seen before, and he began to view her as a woman. Where will their relationship lead now that he has begun to develop feelings for her?
