Kareshi Kanojo no Jijou

Synopsis

Arima's and Miyazawa's grades have dropped. The two of them have been spending time having fun rather than studying. The teachers call Arima and Miyazawa to the office and tell them they need to break up. Miyazawa stands up to the teachers and tells them that they will study, but love is more important than their grades. The teachers call Arima and Miyazwa's parents. In the end, the parents tell the teachers that they have no reason to tell Arima and Miyazawa to break up and trust their decision as they have always been responsible.
