Kotoko has to leave the Irie home, and decides to give up on Naoki. But she is determined to pursue the grueling training in tennis. It so happens that she is challenged to a pairs match, paired with Naoki against the Sudo-Matsumoto team. Naoki loses for the first time in his life, so he decides to coach Kotoko in tennis. On the other hand, Noriko misses Kotoko and goes undercover to the university, where she gets the news that Naoki and Kotoko have had their first kiss.
I feel like that's all Irie-kun has ever 
said to me since we were in high school.
Siento que eso es todo lo que me dice Irie-kun 
desde preparatoria.
Irie-kun no para de decirme 
eso desde el instituto.
D’une façon ou d’une autre,
Eu sinto que essa foi a única coisa 
que o Irie me disse desde o colégio.
