They're all manga with Love Complex and My Love Story having anime adaptions and Love is Hard for Otaku could well be getting one soon. By long form series I mean if you specifically want movies or chaptered series. As an aside, the three I just mentioned have all won awards and/or recommendations of excellence. Edit: More to add, Teasing Master Takagi, Ojojojo, I Can't Understand What My Husband is Saying, Miss Komori Can't Decline, Kaguya Wants to be Confessed, Tomo-chan is a Girl, The Ancient Magus' Bride, Ran and the Ashen World, Red-Haired Snow White. Again, all are manga and some either have anime adaptions out now or pending soon(I still recommend reading both).
