Another uneventful day of school without Sensei passes, which some narrator notes has left the girls all in a state of restless listlessness. One such restlessly listless girl is Chika, who stares out a window, contemplating just why her days have lacked such excitement as of late. Her role as oldest in class would leave the responsibility to reestablish order among the girls to her, but as she asks the nearby Rin about jumping off a bridge, it becomes clear she is unfit to lead. The narrator continues, informing the audience that Chika's recent lack of need to be on guard has sapped her of the motivation she once had, and - whilst she dreams at night of being whisked away by the wind - she knows the only thing which will help her regain her momentum is herself.
After clarifying her earlier bridge comment, Chika asks if she can be allowed to vent a small bit, lacking other friends to do so. Rin's fine with this, though warns she might be little help. Chika prefaces that this will be about guys, something she assumes Rin will have trouble with due to her soreness over her breakup with Otoha. She reminds Chika that Otoha was a girl, though concedes the general topic will be difficult given her own failures. Chika quickly assures her that the relationship failing was Otoha's fault, before moving on.
To no one's shock, Chika reveals she's talking about Sensei. His two months of absence, combined with their lastfew interactions have given her the impression a gap has formed between the two of them. She specifically cites his recent promise to babysit, and how he disappeared hours prior without telling her. Rin's surprised by this, explaining that, given Sensei's current mental state, his not feeling emotionally ready to babysit makes a lot of sense. Chika agrees, realizing she got too caught up in excitement to really consider how he'd feel. How Sensei feels has been a real concern for her as of late, recounting his recent denial of time together and worrying about the intricacies of his decision. In this regard, Rin is unable to help, and the conversation moves on.
Chika decides to focus on what steps to take to avoid disaster instead, hoping this situation will soon blow over and she'll have more mistakes to learn from. Rin questions if there have been any mistakes on her part at all, feeling that she's extremely level-headed and rational. Chika asserts that small mistakes are inevitable in all relationships and that the real struggle will be accepting that Ami can help whilst she can't. She takes the opportunity to insult Ami, something Rin objects to as Ami isn't around to defend herself, and she clearly needs serious mental help if her state of mind has led her to say uncomfortable and hurtful things to all the class. Chika quips that little exists that could defend Ami from her, especially with the blackmail she's taunting with. She does, however, take comfort in the fact that Ami is unlikely to do anything that could seriously damage Sensei's image.
Rin tells her that she's thinking too much about him and too little about her, warning that such one-sided expectations are what caused lots of fighting between herself and Otoha. Chika dismisses this advice, claiming that Sensei is not nearly as evil as Otoha is. Rin finds this hyperbolic, stating Otoha's only crime was not actually loving her – Chika retorts that the real crime was her pretending she did.
Her venting finished, Chika invites Rin over to her new apartment as thanks. She turns down this offer as she's currently trying to get promoted and needs the hours to prove her worth. After Chika thanks her for listening, Rin takes off.
