Futaba Yoshioka used to be a popular and gorgeous middle-schooler who was widely loved by the boys but shunned by the females. Nonetheless, she was able to dismiss all of this since the only opinion that actually mattered to her was that of Kou Tanaka, a classmate with whom she previously shared a rainy-day shelter, as well as a number of other priceless and memorable moments. She even made preparations to see the peaceful and innocent guy at the summer festival, but a simple misunderstanding, followed by Tanaka's absence, left her alone in the halls of her school.
