Why do I like this girl so much all of a sudden?

Like, I don't get it. Before I met her, I would say she isn't my type but then I met her and she just like fills my mind I guess. <- I don't want to sound cringy there by the way lol but this girl (looks wise) is nothing like any girl I have liked. Does anyone have an answer for this?
