Sharing Our Innermost Thoughts

There’s a guy in my school, like recently only he started being so weird, like before i didn’t notice is presence or even though he is in my school i just didnt care about him, but now whenever he comes around me i just feel something strange , i don’t know , its just i feel or sense something,maybe he has a crush on me or maybe i am overthinking idk .what do y’all think?
