Why do I keep thinking about a guy who isn’t my usual type?

So there’s guy, who isn’t my usual type because he’s half of the head shorter than me, I usually don’t date guys who are shorter than me.

But I feel like I’m naturally drawn to him, even when we first met, I feel like there’s some chemistry between us, it’s in my gut feeling.

Now I keep thinking about him, I even feel nervous being in his presence and my heart beats fast when I talk to him. But I don’t wanna identify it as a crush because he’s not my type..
I have no idea why I feel the way I feel..
