Hirano to Kagiura is my favorite romance manga in general, it's really cute but it's unfinished and they're still not together after so many chapters...
Also a short story I discovered is Kimigazer, it's really short and the artstyle is so adorable, I really recommend that 1 it's so underrated

Oh also Faded First Love/Kieta Hatsukoi! (It's called Faded First Love on Mangago), I originally watched it as the drama and just discovered it has a manga, the story is so adorable and I love the artstyle in the manga. And in the drama they're also super well-casted. But of course like every highschool romance there's so much second-hand embarassment but when u read romance u just get used to it lol, it's hella cute tho
