Kashiwagi's boyfriend goes back to Shirogane for more romantic advice while Kaguya eavesdrops again. Thanks to Shirogane's advice the first time around, the boy has been dating Kashiwagi, but a month has passed and the two haven't even held hands yet. To Kaguya, the question of what to do in order to hold hands is so simple that she's disgusted by it, but for Shirogane, who doesn't actually have any experience when it comes to romantic relationships, it's a relief since he feels capable of addressing the problem.

But the day before the event, Kaguya's father suddenly summons her home to Kyoto...
