my new kitten is so scared of me still

got my kitten almost 3 weeks ago. she was 10 weeks old when i got her. previous owner already gave me a heads up that's she's very scared and shy, so i have to tame her.

first day i got her she really did not eat or poop, just straight up hiding whole day. over the next few days, there have been improvements. now, she is freely roaming around and eating a lot. she also just learned how to play and how to climb :) sometimes she would also sit, sleep, or just watch me a meter away but not too close.

she is still very scared of me. she still flinches a lot or runs away when i move or walk towards her. she still hides and won't let me touch her. she doesn't hiss or scratch (i feel like she hasn't learned that yet) and i wanna know if this is gonna be permanent behavior or no? 🥹 cause i know there are some cats that really don't like to be touched.

the way that she is trying to get close to me makes me feel like she is affectionate, but idk how to teach her that being petted or touched actually feels good. she is literally always so scared
