Thanks for the snarky undertone, appreciate it.
There has never been any other person on her older (most of them now deleted) ig pics. I have pics of her from ig uploaded form dates dating back to 2019. There might have been older pics I missed tho. There have also not been any other people with her on any other of her social media. She clearly is keeping her private life private (except her full real name, which she might not have thought about keeping private at that time). Some pics from ig were clearly taken by another person for what it is worth. Most pics are selfies. What she presents to us is all just about her showing us her cosplay and body, not a diary of her life, so not much to take from there if you wanna learn about her personal life.
But if you want me to give you some super stalkery details: some time around 2022 i believe she moved to a new place. She probably has dark grey cat, which she might have gotten in 2019 (probably born then). She has a skateboard she can actually ride, i believe. And an e-guitar she probably, like most of us e-guitar / e-bass owners, cant really play well
She still looks fucking cute without makeup btw, there is very few rare pics without eye makeup. Her specific and perfectionist style, cute face together with that deadpan face-expression always makes my autistic heart melt. That said, you gotta be aware that those ig and fansly pics are heavily edited, filtered and optimized, in reality no one of humans looks perfect all the time and you get a better sense of reality on the older less edited pics - still top cute in my mind tho.
Btw I think she must be tiny, like 1,55-160m or something based on reference object next to her. I m just stating this as an observation, shouldnt make any difference how tall someone is really.
Sorry got carried away going through old pics, going back to your question: There is certainly a chance that she is or has been or will be with someone. She surely keeps her place tidy as fuck though, so that is quite difficult to tell this just from the pics alone. All I can say is that so far there were no giveaways that there is somebody, but there can always be someone and you would not be able to tell without a clear indication. But then also you don't know if she is not actually attracted to other girls, or robots or who knows really and the question you gotta ask yourself is what why is matters: would it change anything for any of us except maybe destroy someone's deep romantic fantasies and feelings if having such for her, but that is in the end just gonna be self-inflicted pain either way and better be destroyed soon. I d recommend to redirect those feelz, if you carry them to actual people you could meet and date in your actual life rather than a girl in a post-soviet country who sells risque nudes on the interwebz to afford or improve her lifestyle, and who you are realistically never going to meet - and if you met her maybe wouldnt even get along with because all there is between any of us fans and her is that we are drooling over her (pretty one-sided) and that is not a basis for any relationship with another human being. On top of that she also is clearly not the chatty type of person to strangers, who you therefore had a chance to befriend or get to know online much.
I think she introverted and very polite and nice but also shy and self conscious and probably a bit pedantic and perfectionist. If I was her and was with someone (of any gender, or a robot) i would keep it secret like they do it for those pop band idols and k-drama actors, to keep people dreaming

I attached a pic of what i think is her most genuine strong smile. Btw she also has fine teeth, so she is not avoiding a smile to hide her teeth, i think just being shy as others said
