Sensei heads to the convenience store in the Old District, hoping to spend some time alone with Noriko, being surprised to find Kirin there as well. The two girls continue their usual banter with one another, and their comfort with being so crass all the time continues to surprise Sensei, especially considering their near-opposing stances on love. The conversation eventually comes to an end though when Kirin decides to head home, being forced to watch her parents' wedding video with the rest of her family. Being busy that night herself, Noriko suggests Sensei walk her home so they can talk.
The two walk mostly in silence, only breaking it as they walk around the side of an old river. Kirin tries to pry into Sensei's relationship with both Makoto and Miku and after having her attempt repelled, is reminded that she's currently mad at Sensei – Not only for abandoning Noriko during Christmas but also neglecting to inform Kirin about him and Miku. Sensei fails to see why he should regularly keep Kirin up-to-date on his relationships in the first place, or why she'd even care. While she admits dealing with feelings is uncomfortable for her, she confesses that being excluded from such a big development involving two of her favorite people makes her feel left out. In addition, it makes her feel weird making a bigger deal out of the situation than anyone else.
Sensei quips that her ability to play on both Miku and Noriko's “sides” is even more strange, though that Miku herself wouldn't mind due to her "openness". Kirin agrees, being equally as surprised by it, and wondering if Miku was possibly influenced by her. Sensei dismisses the idea as Miku seems genuinely open while Kirin herself is simply pretending to be. To prove his point further, he proposes a hypothetical – If he chose to abandon his current life and run away with Kirin, would she accept that. She answers "yes" easily, and wonders why they can't just do that in the first place. Sensei answers that the two of them care about other people more than they admit and are simply hiding it because they both consider it a weakness.
The two finish the walk back to the Kanda residence in silence, although, along the way, the two allow themselves to show their weaknesses.
