During the Summer festival, fireworks burst in the sky, sending sparks dancing overhead... and between Nao and Kyosuke! Now closer than ever, Nao quietly wonders if her friend might become something more until Tomoyasu speaks the words she, he, and Kyosuke are thinking: "Are you guys together now, or what?" Nao is devastated when Kyosuke immediately denies it, and Tomoyasu explodes over his brother's indifference. Finally, he declares war with Nao's heart on the line, but Kyosuke is still unmoved... or is he?
