Do guys smile "mischievously" at girls they like?

I get this vibe that my crush is being mischievous or playful in the way that he smiles at me. I have read that guys smile kind of slyly or sheepishly at girls they like because they feel kind of mischievous around her?

Not sure if there is any truth to that though lol.

There have been times when I smile warmly and make eye contact with my crush that he tilts his head, raises his eyebrows, and gives me a lopsided grin.

Other times he will grin at me when making eye contact and look away and grin some more. He will often smile really big while saying something..

If we talk and I smile at him, he will smile back at me but sometimes shifts his eyes to the side.. Basically smiling but not looking at me directly.

Am I right in that there is something mischievous in how he smiles at me? Or am I reading into nothing? I'm just curious if guys smile "mischievously" around girls they are attracted to/ interested in.
