I’ve started wondering lately if I’m kin- at first when I saw the character I was like, “that’s me- mannerisms, personality, I feel like I know exactly how they feel” and over the past couple months it’s evolved. When I see them I can’t help but identify with them on an emotional level and the “that’s me” feels like “that’s me, that’s me in maybe the right body or a different universe, not sure yet”. I feel silly getting protective sometimes because they feel like an extension of myself..?
That sounds like fictionkin to me. Congratulations on the beginning of yoru awakening. It will be a long journey, but one that will lead to a better understanding of yourself. I recommend continuing to look inside yourself, and explore this side of your identity until you are comfortable saying firmly if you are fictionkin or not with.
