What would you do if you liked a girl who you couldn’t read?

I’ve liked this girl for a year. I can’t tell if she’s interested in me or not. She doesn’t show emotions and she’s very quiet and to herself. Sometimes she’s super smiley and approachable other times she wears headphones and avoids eye contact and seems to be in her own world. I’ve approached her and said how are you and all I get back is a smile and good how are you back. I’ve told my friends about her and they can’t tell her feelings towards me either. What should I do?
