Itoshi Aida lives next door to Ruru Yumemi, a first-grade elementary student. He is Ruru's classmate and the secret object of her affection. Akubi, a magical entity dwelling within Ruru's vase, endeavors to employ her powers to foster a closer bond between Ruru and Itoshi. Despite her varied magical interventions aimed at uniting them as friends, these efforts consistently fail. Itoshi serves as the focal point for Ruru's unspoken feelings within their narrative, while Akubi's persistent yet unsuccessful magical attempts to connect them form a recurring dynamic.
