Falling in love with my stalker

I was going to my locker when I fell to the ground and my books falling to the ground like dominos. I look up to see the person had fallen to the ground as well. He gets up first and wipes the dust off of himself. He walks over to me and holds his hand for me to take it. I grabbed his hand and he pulled me up with ease. After he helped me up he walked away without a word being spoken. I look at him as he walks away and just stare with so much running through me mind. "Who is he" and I just leave it at that.
