Explain my cat pls

Aight so my cat is adorable, she is a female and she is 5 months now.
Basically she confused me because every other cat I had has wanted to square up with me.

Within like 30 mins of picking her up in the car and meeting her...she was purring and resting on me...and then we went to the house and after exploring she started kneading everyone.

Then, she started kneading and pretend weaning me every night before sleeping and she stopped kneading everyone else.

She used to only purr with me but now does it with everyone else, still no kneading.

She doesn't like to be separated from me.

Also she used to sleep next to my feet but now likes to hold my arms or rest her head on my arms while she sleeps.

Why is she like this? Does she like me? Is this normal for cats or is she just friendly? She never ever scratches us and only gives gentle bites, why isn't she trying to hurt me. Also whenever we try to carry her she resists for a bit but if you keep holding her she starts purring again and when u let her go she won't run away.

But when we brought her to the vet they were talking about how she was going crazy.

I'm so confused I've never had a cat like her before (ಥ﹏ಥ) she makes me think that she likes me but idk.
