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.
Oh, I heard you live in 
the same house with him.
Oh, he oído que vives 
en la misma casa que él.
Oh, dicen que vives en su casa.
Il m’a dit que vous habitiez
dans la même maison.
Ah, eu soube que você mora
 na mesma casa que ele.
