you should check out the mangas by Junko
she drew Recipe no Oujisama and i really like her other stories
Kimi Note; Konbini-kun; Star Like Words; Kasa no a, Futari; Abarenbou Kareshi
Gochisousama isn't by her but it's another manga i remember reading it
it's pretty good imo

Rainbow Rowell's novels especially Eleanor and Park, and Attachments.

konya mo nemurenai, recipe no oujisama
i can't think rn since i just woke up but those are 2 mangas
