After their first kiss, nothing changes between Kotoko and Naoki. Kotoko is now a college student, and a powerful love-rival Matsumoto Yuko emerges at the university. Kotoko and Naoki are in different departments, but Kotoko pursues ways to get closer to Naoki. She joins the tennis club he's in, but she cannot keep up with the training. On one of those nights, Kotoko's father decides to leave the Irie home, because he wants Kotoko to give up on Naoki. This comes as a big shock to Kotoko.
You and I might not be good students,
Tú y yo encontraremos aquello
 que se nos da bien.
Podremos encontrar 
algo que se nos dé bien.
Même si toi et moi,
on n’est pas doués pour les études…
Eu acho que ainda podemos achar alguma
 coisa em que somos os melhores.
