hello , I’m new to this “fictionkin” concept.

Even though I’m from Gen Z , I don’t know almost anything about internet terms , but after going to cosplay conventions , I met a friend who told me about “fictionkins”. And alright , now I discovered something I was trying to ignore for years (shifts and kin memories) actually happens to a lot of other people . I’m getting used to these terms , so please help me in anything in case I get something wrong. For what I’ve seen , I “identify” has characters from anime . Hello , everybody .
