omg kk hiiiiiiii. o/ o\ o/
my story is kinda similar to yours, i met a vriska (who i am no longer friends with, long story) around 2024, and them and the people in the server they made eventually made me realize that i'm 8oth alterhuman and a trans woman!
specifically the system thing came a8out from me showing to two of my friends what systemhood is and thinking "heh. that means i'll never 8e a system! i'm one of those people who can make anyone a system, 8ut not myself." (clueless)
