@himeleth i assume she's 16 and of the age to give consent in Japan, since you know, high school 16, 17, 18,
and age gaps mean nothing to me - boys her age can be just as harmful if not more, it all depends on the character of the person and their relationship dynamic
And as long as it's not human trafficking or illegal prostitution,
is it really that weird for a high school girl to have a sex life with an older person?
