"My place is close by... why don't you stay and rest?"
On his way home from a drinking party, Kazuya was approached by his ex-girlfriend, Asami. Asami
told him that she had lied about having a boyfriend, and Kazuya decided to seize this opportunity.
A few days later, Kazuya went to the beach with the people from the drinking party, and he resolved to use this two-day trip to find out how Asami felt and get back together with her.

When Chizuru woke up, she was in the shallow waters of a small island. Finding Kazuya lying unconscious, she remembered that he had jumped in to save her when she fell into the sea. Chizuru called out to Kazuya, but there was no response. "Stop messing around!! Wake up. Hey!!" -- Chizuru leaned closer to the unresponsive Kazuya...
Meanwhile, at the Kinoshita house, plans were being made to go to a hot spring inn deep in the mountains to celebrate Kazu's recovery.
