Warning: This is going to have just age gap relationships so I advice if you're uncomfortable if the characters are underage for the MC it's best you leave.
This may irritate you but I did warn you this has a lot of R18 scenes that could have you question why. Lots of degenerate explicit scenes.
I advice anyone to be 18+ not meant for the regular audience.
It has some realism into it but still fanfiction.
