It’s possible that she’s also interested in you and just waiting for you to confess your feelings first because many women usually don’t express their feelings until the man does.
Just continue being noticeable and staying close to her because that’s often how girls start to develop feelings, especially if you’re playful and you make her smile. I’m sure she might end up liking you too.
If you really like her and you’re both at the right age, try courting her in your own way. You might have a chance, and she could say yes to you.
