Help with studying abroad

Hey guys! I'm studying abroad in a korean university and theres this korean girl that i like in my class. I sat next to her and I noticed that she had a powerpoint slides when I don't think the professor even uploaded it. At the end of the class, I asked her genuinely where she got the powerpoint slides and showed me through my cellphone. Then I made a joke and she giggled and then we split up. I know that it sounds very lame and I know she is not attracted to me yet but its a very small step. The thing is that next class, since you choose to seat in any other seats, it'll be weird if I sit next to her again. Do you have any advice for me?
