At the end of the year, even though everyone has different feelings, they all spend the last days of the year in a busy fashion. This spirit is also present in a new town Megumishi, close to the city. On Christmas Eve, an extremely ordinary boy, Naoto, met a strange girl. Even though she hadn’t met him before, she had a sense of déjà vu. This was when the story of Naoto and three girls begins. One wished to protect her happy time. One unconsciously tried to obtain something. One strove to achieve a precious goal. [From Hau~ Omochikaeri!]
