My Girlfriend Is Shobitch

Shinozaki tells his high school crush that he has feelings for her; the straightforward Kosaka takes his confession more seriously than he expected; she decides to learn how to be the best possible girlfriend.

Kosaka and Kanata compete over Shinozaki's attention; Kosaka convinces Ariyama to teach her how to cook for Shinozaki's benefit.

Shinozaki goes to Kosaka's house and finds that quirkiness runs in the family; Kosaka prepares for her first date with Shinozaki.

Rina, a new girl at school, joins Kosaka in her study of males and branches out to find others besides Shinozaki.

The girls find themselves in several small but awkward situations; Kosaka goes overboard trying to anticipate Shinozaki's needs, proposes more sex education in school, and comes down with hiccups.

Kosaka befriends Seiya, which triggers Shinozaki's jealousy.
