I went up to the guy I like and scared him

For the past couple of weeks i’ve been wanting to talk to this guy in one of my classes. So this morning I woke up determined to talk to him, I got ready and made sure to look good. Lol

So we were walking across the street on to campus and I thought it would be a perfect opportunity to start a conversation.

So I said “hey you’re in my class, I was wondering if you know if we have a quiz this Thursday?”

He look at me shocked and said “wait what?”

Then I repeated myself..

& he said while walking toward another direction “oh yeah, we do. We have one every time.”

He kept walking and he said “yeah, it’s over oral anatomy lots of info, see you later” then proceeded to walk away.

I don’t know if this is helpful in any way, but I’m Hispanic and I’m only into asian guys, lol. The guy I went up to is Korean and maybe they’re not used to girls approaching them?

I don’t understand what I did wrong in this situation? Did I come off to strong? Did I scare him off?

I have to see him in class again and I’m too scared lol .

Add: I always catch him staring at me in lecture, for lab we sit across from each other & we often exchange glances. I thought he was maybe into me but I guess not? I know he’s not dating anyone and that he’s single.. maybe he’s not into Hispanics ?
