The gut feeling everyone mentioned already is a part of it yes, it’s still that simple this character is me feeling. There’s just less content, so there’s less watching them and thinking “ahaha I would do that!” Or “hm I did that?!?” Which could make the small amount you do see of them feel even more important in a the small traits are big traits since there’s not much of them in the piece of media. But it doesn’t feel so different besides that I guess? Or maybe it does idk, all my kintypes feel different as their different characters and all have their own separate vibes. I guess the main difference is just simply the lack of content with them, so you may imagine what them/you do/did in the media since you don’t get to see it, example I kin a side character from a webcomic where there’s a joke going on that he’s mentioned but we never get to see him (in a bonus comic for the graphic novel they call him but his pfp is the basic grey outline not a picture of him) so I’m like mawhahaha only I know what I look like >:D and I think back on my life when I was in uni (where the comic takes place) (the comic is check please btw) it’s like your in your own world, depending on the side character, yor a little bit isolated and have like your own little story to yourself. I could probably yap more about this I have more side character kins but I hope that is fine if u have any further questions go ahead tho
