I want a short High School sequel where a boy tries to pursue Yamada, and a girl doing the same with Ichikawa.
They are going to different schools so won’t be seen together, and thus people will think they are available.
It will be a classic romcom where they think they are making progress with them, and fantasize that they share all their first with their arch other, not realizing that they been there and done that long before.
Something like that one manga /a/ keeps raging about, but more comedic and far less mean spirited.
