One day, Charlotte Bennett comes to study in Akito Aoyagi's class. With her neat and elegant demeanour and cute appearance, all his classmates are attracted to Charlotte, but Akito secretly feels that she lives in a different world and takes a step back from her. However, Akito's daily life changes dramatically when he saves Charlotte's lost sister, Emma. The three of them play dominoes, sit around the dinner table and go out together. As they spend more time together, Akito and Charlotte grow closer, as gently as awkwardly.
