All the girls compete on spending time together with Kaoru. But when they hear that the poor and tired boy has a deadline to keep for finishing an important report at grad school, they now try to "help" him in different ways. Only after Aoi saved Kaoru from another of these "attacks" and scolded the girls for preventing Kaoru from working, they leave him alone. But when the report is finally finished, this is an event to be celebrated.
