After Shigeki’s heart attack, Naoki decides to help out with company business until his father recovers. But Naoki discovers that the company is in serious financial trouble. Kotoko cares tirelessly for Naoki, as she is concerned about his well being, considering he gave a leave of absence to school, and maybe would have to abandon his dream of becoming a doctor. On the other hand, Matsumoto decides to profess her love to Naoki. Kotoko finds out about it, and then ...
When his dad's health recovers, 
make sure you come back.
Cuando el padre se recupere,
prométeme que volverán.

dès que le père d’Irie ira mieux.
Me prometa que quando o pai dele 
ficar melhor, vocês vão voltar.
