Season 1

Takase's crush wants to talk to him about something, but she beats around the bush. Minagawa confesses to Furuya-kun -- or does she? Akagi catches Kaji smoking. He could rat her out, but he has different plans. Saasahara wants to confess to her crush before he graduates, but her unfortunate defense mechanism makes that difficult.

Furuya's sister, Hotaru, doesn't want him dating Minagawa -- or anyone, for that matter. Kaga has a hard time caring about anything, and Sasahara has a hard time pitching anything -- especially the astronomy club. Goda is dense as hell. Takano is about to walk home in the rain, when Sugawara offers her an umbrella. She, too, is dense as hell.

Chiaki and Kana have apparently been dating for a year, but you wouldn't know it. Matsuura gets rejected. Her senpai annoys her out of her mind. Yamane's crush, Kurihara, asks her out on a date. He malfunctions. Sugawara offers to help Takano with cleaning duty. He thinks she thinks he thinks she thinks he's asking her out.

Kana finds Chiaki's porn, and so they get it on. Kaji calls Akagi out on manipulating her. Minagawa tortures Furuya with mind games some more. Takano is still denser than lead.

Kanda decides to text her confession to her crush, Takase, but a race condition results in a deadlock. Kaga's childhood friend, Nanase, joins the astronomy club, but she seems to have an ulterior motive. Goda and Kamine are finally dating, but he has trouble communicating his feelings.

Akagi is tutoring Kaji, but he keeps flirting with her, driving her to show her bad side again. Kana and Chiaki discover that mothers are a very effective contraceptive. Kurihara and Yamane make plans to go to the movies, but he that realizes he'd had plans to go to the movies with his (only) friend, Motoyama-kun. Dating master senpai is back, this time apparently wooing Kazuko.
