Would he lie to me?

From my previous posts I'm trying to figure out if this guy I met really wants to be friends with me I'm a 15 male and he's in some of my classes and I really want to be friends with him but he doesn't seem like he wants to be my friend he's a pret6chilled guy one of the people that sits in the bad of the class and might say something snarky to the teacher to get a laugh he's not a bad person from what I know he seem pretty friendly I'm just sure if the reason he doesn't interact with me more is because of me I don't know if I'm being too friendly or what.... or if I'm just overthinking everything and being paranoid which in turn would probably drive him away I'm just not sure can any of you guys help me if you need more context you can go see my other posts
