These three episodes do what the main series only hints at: they let you watch real couples actually be couples, bickering over stupid things and figuring out how to live together without losing themselves. The OVA doesn't pretend love is a climax you reach; it's the daily work of two nerds choosing each other in ordinary moments. You get side characters with the same messy, unsentimental depth the show promised, though the second episode fumbles its landing hard enough that it nearly derails the whole thing.

Three OVA episodes of a comedy romance adapted from Fujita's josei manga, originally bundled with special editions of manga volumes 7, 10 and 11. The first goes back to high school: Tarou Kabakura, a third-year student and captain of the boys' volleyball team, is pestered constantly by the younger Hanako Koyanagi, who leads the girls' team and wants the courts for an upcoming match. When he says no, she produces photos that reveal his secret otaku hobby. Afraid his teammates will find out, he gives up the courts and coaches her one on one, and a lasting bond starts to form between them. The second episode expands on the relationship between Naoya and Kou, and the third adapts the manga chapters about a company trip.
