Since middle school, Futaba has always believed that boys were too rough and violent. Kō Tanaka was the only exception, and Futaba wanted to know him better. The two share brief, sentimental memories—including a plan to go to the summer festival together. After accidentally telling Naitou, Kō's friend, that she hates all boys within Kō's hearing proximity, she worries about his opinion of her but convinces herself that he understands he is an exception. The summer festival arrives, and Kō doesn't show up. Returning from the summer vacation, Futaba hears that Kō transferred to another school without explanation. Futaba realizes how much she liked Kō and regrets not telling him how she felt.
