Shi ni Modori no Mahou Gakkou Seikatsu wo, Moto Koibito to Prologue Kara is good but incomplete. Also has fantasy elements.

If you're okay with the older stuff, Dengeki Daisy is nice and decently long.
Flawless is also a bit old, but is complete.(Webtoon)
My reason to die is good, but the school life aspect only lasts first half.
Okashiratsuki is less shoujo more romance. 24ch and cute art.
Doridosim (old/Webtoon),
Strobe Edge(same author as Ao Haru Ride)(old/complete)

I gotcha on this dear, enjoy <3
