Describe a situation when a boy and girl fall in love at first sight?

I don't know If you mean like this but ...

Explanation:

"The first time I saw my now-husband, I was 15 years old. It was summer, he was my waiter, and as we locked eyes, I swear everything around me slowed down and I knew. It was only a second as he was walking around a corner, but he remembers that second as clearly as I do, as if it were yesterday. I had never seen a more good-looking guy (granted, I was only 15, but I had had my share of boyfriends). That night, we met up for a movie after his shift. He kissed me for the first time (although he will tell you I was the one who kissed him), and I swear, my breath caught, my head swooned, and we both knew that this was something more than a passing fling. It's now 15 years later; we have been married for seven years and have three children who are the lights of our lives. I get butterflies every time he kisses me, and we both still talk about that very first time we saw each other and how we knew, 15 years ago, that something clicked, something connected between us. If anything deems to be called love at first sight, it would be this."
