Why are we in love (Last man)

I love you part one
here let me start you at the beginning I'm in high school my name is Karly I can't get a boy but I will have to live with that... I was walking through the school hall I bumped into Justin he's one of the most popular guys in the school I was so embarrassed but he quickly sad sorry and introduced him self.
The next day I was deeply starring at him and he looked at me he smiled I smiled back and then guess what happened next the bell rang at the most perfect time I wonder if this school is cursed but just for me!!! But just when I thought that Justin came up to me and asked me for my number I quickly pulled out my phone not thinking anything through and he left. I was waiting for a call from him (2 hours go by) (another hour goes by). I was about to give up till the phone rang it was my mom sadly but then 20 minutes after my mom called Justin finally called we talked for hours I thought he was the one for me.....
