>how many plot points are left to rot unutilized?
Chizuru's work as a rental girlfriend outside of her dates with Kazuya.
Kazuya's friend circle and by extension the girls from Mami's clique.
The university setting for the most part, if not for the drinking parties the plot could be easily fit in a high school.
Chizuru's acting career (we get some glimpses from time to time, so it's not that bad)
The movie, after the premiere it might as well never have happened.
Chizuru and Kazuya being neighbors hardly ever mattered
Ruka's family situation and how she constantly lies to her mom.
Ruka being a JK.
Sumi had her spinoff (I can't believe that Reiji's assistant's manga already is at 100+ chapters), but Reiji now has the second manga so it's probably dead dead.
