When I first saw you, I saw smiled.  My heart was pounding and when I saw you again, I was nervous and felt like a nervous wreck.  Someone who's apparently out of my league is someone who I want and love.  Love isn't easy, but you'll need to fight for it to have it.

"When I first saw you, my heart was pounding.  You gave me that..."

"...feeling that you can't describe.  It's like love at first sight."
