Have you read Koisuru Harinezumi? And I also love Kimi ni Todoke and Ao Haru Ride but they are popular so you might know them already.
this one cute if you're okay with older girl x younger girl (well, they only one year apart) http://www.mangago.zone/read-manga/toshishita_no_otokonoko_hiro_chihiro/
this one has love triangle with good art+story http://www.mangago.zone/read-manga/haru_matsu_bokura/
I think you probably already read this bcs it's quite popular but nevertheless, it's a very good manga

My recs probably not that good since I don't read shojo that much hahaha sorry
Can anyone please recommend me good Shoujos with nice artstyles, cute couples, love triangles, school themed, preferably with no tragedy (i can handle drama 100% but tragedy is way out of my league)? Thank you so so much in advance!! (●'◡'●)ﾉ
