I consume a heck lot of manga but some of my favorite manga features grooming and rape. E.g.
Hana to Akuma, Fruits Basket, unbalance x unbalance, kare kano, kou 2 time leap, etc.
Particularly female teacher is one of my biggest types, (so much that I actually enjoyed kiss x sis, up until the guy started cheating on the teacher with piss girl and I dropped the manga), they are so cute but also so fucking rare.
Yes I consumed more
medias than any of you!
I liked the female teacher archetype enough to go on manga updates, looked for "older female younger male" tag and read every available title on the site (bar the hentai ones, but cuvie has some great oneshot featuring female teachers) once upon a time.
And these are the "light hearted ones" compared to the ones you listed.
