Is this attraction or just nothing?

So I met this girl on my class. And she was doing her work and I was doing mine. She was sitting next to me. And she started asking me questions and we were soon talking. And she wanted my insta so I gave her. She added me and after class she wanted to go hang out with me in the park were there was a drama play going on.
She asked me if I was single and all that. Then wanted to walk across the park together. She laughed more than me. And also after all that took my number.
It was like she was genuinely having fun in the convo.
And during the play she wanted to sit together and wanted "my company".
And also laughed and touch me during laughing.
Now, she does late replies but short ones
I remember she said that she would disturb me much since I am having a important time of the year.
Is this some kind of chemistry or I am just overthinking?
