I introduced a social hierarchy system which classified people into three tribes "dirt", "cleanser", and "glue". Glue remains unphased by the other tribes and had the ability to connect different groups. Too much dirt can turn you dirty, whereas a cleanser can clean you up.
It took a few months and the gorls would actually live by it. White selves.

It just turned out when people matured and bonded in the last year of high school nobody wanted to connect with a social manipulator who is overtly messy.
But really I wasn't going to assimilate to these white privileged middle class Germans anyways, so good riddance.
