Koibito ga Dekinai to Taigaku ni Naru Gakkou ni Nyuugaku Shiteshimatta Gal to Otaku.

At Riaju Academy, a school where romance is mandatory, a gal-type female student named Date, determined to abide by the school rule that "students will be expelled if they don't find a boyfriend/girlfriend within three months," devises a plan to avoid expulsion by pretending to date Sugyo, a male student who also doesn't have a girlfriend. However, neither Date nor Sugyo have any romantic experience, so their pretend relationship ends up being a haphazard affair.
