What do u like in a girl main character?

I write as a hobby. I already have a part of her created, but I'm struggling really hard to develop the rest of her. I want her to be a likable and unique character. I don't want her to be the classic "good and nerdy girl", but I don't want her to be a bad girl either. (It's the first story I write and I writing cause I like and to distract myself. Its "enemies to lovers" coded) Someone pls help me 😭😭
