Have you ever experienced this before? Any suggestions?

There's this girl in my class that's talked to me just like 4 times since we started high school 2 years ago. I find her pretty cute but i've never ever showed it neither i've done anything to try and get to talk to her more because i'm afraid to ruin everything. We started following each other on instagram three months ago, and for the first couple months she was just viewing my stories (photos and music) as normal. Then, out of the blue, she started liking all of my stories (i've not changed format or anything), even the music-related ones (i listen to metal while she listens to olivia rodrigo and stuff). I talked about this with my friend (also a classmate, so she knows and follows both of us) and he helped me by posting a story with the same kind of music i post and we both listen to. She didn't like his story and kept liking mine. As of today, she's liked aroud 15 stories i've posted, only 5 of which are photos that she might like just for the aesthetic. Should i like her stories back or do something else?
