I need help

I have a situation where there is a girl in my class who is giving me hints ( alot of hints in class) and I think she is pretty cute herself so I was thinking of approaching her but the thing is today I just saw her post a story on insta( I was stalking) the story was of a boy with the song cigarettes after sex and their was an emoji kissing the boy's chicks so I am kinda confused and don't know what to do

Feel free to ask questions
