What makes me look asian?

Edit: dm me for pics

I’m Half German and Half Korean but I’ve been never mistaken for anything other than Asian or half Asian. I don’t have the stereotypical Asian features (monolids, flat nose, etc), I have light colored eyes, and brown hair. I feel like I look more white than asian but I also wouldn’t be able to pass as full white. This brings me back to my question, what makes an Asian person with Non-Asian features look Asian?
