Kijima-kun
Shitteru Yo.
Doukyuusei (NAKAMURA Asumiko)
Iberiko Buta to Koi to Tsubaki (been a LONG time since I read it so I genuinely can't remember if there were toxic traits. I'm like 86% sure there wasn't. Also, while I like the art style, it might not be everyone's cup of tea.)
Window to Window (been a while since I read this one too, but I don't think it was super toxic)
Encirclement Love (doesn't necessarily center around school, but cute relationships and art)
