sry- a lot again

lol ok now I'm invested, have you tried:
- Hanatsukihime (demon x human short but makes an impact)
-Keishichou Tokuhanka 007 ( lil bit of solving crime but mostly just funny+fluffy)
-Masca ( all the magic things and I'd say the art style is kinda unique)
-Dance! Subaru ( not romance based, all about a girl becoming a dancer and there's a sequel too )
-Ciel -the last autumn story- (its not exactly complete translated, I think it's 1 ch away but i just read a summary of it online. I think it's a pretty refreshing story with a strong FL)
- Kore wa Koi no Hanashi (Large age gap ML is a writer, darker themed compared to what I've recommended before)
-Hana no namae (pretty much the same thing as the one above but a little lighter)
Can y’all recommend me good completed shoujos. I always like lowkey underrated good shoujos. Especially old ones. I like good character development or plot too, doesn’t have to have romance. Thanks friends!
