2nd story, they had no contact for 9 years and everyone calls him a groomer

imma just elaborate that while it does feel wrong, (and from someone who got grooming attempts as a minor), sensei didnt really do anything to make the student like him nor manipulate him. he was just being a good teacher.

They're prolly kids who don't know the real meaning of grooming (￣∇￣")

Yeah you're prolly right. I'm so old i forget that kids reign over the internet nowadays
