In this chapter, we learn that Shuji and Tomoyuki are in love. They're in the middle of a scene where they're going to act as lovers, and Shuji wants to play the part of a guy who's in love with a girl named Tsubaki. He wants to make sure that she's not showing her back, so he wants to film her with her upper body in a nude position. He also wants to use a special sports drink to make it look like he's having sex with her, so that she won't be able to tell him that it's her back that's sexy. They decide to cut the scene short so that they can use the special drink to taste Shuji's new love interest's " drool" . They also decide to use the sports drink as a fake kiss, so Shuji can't say that his girlfriend's back is "poisonous" to her.
