Peer editing- describing someone

My partner, with whom I use to be in all my classes, at first time was someone introvert and shy from my point of view, but just because I didn't know her at all. In addition, she told me: "at the beginning I'm not so talkative, but I'll be so different in a few days" so now I can say that she is someone happy, funny and attractive, although she looked like a person "without feelings" before knowing her (I must explain I say this with respect and a friendship love). Also, I would say she is extrovert, smart and thin physically.
I like my partner more and more.
