At first, everything will be miserable because you'll be reliving all that made your actual high school experience a nightmare, and you'll have a tough time fitting in.
Except — uh oh — you were so drunk that you forgot to wear a condom, and one of you got pregnant.
You decide to keep the baby and give yourselves a chance at a real relationship.
You'll stay friends for years — decades even — until you hook up and it gets temporarily weird.
But then, on New Year's, you'll make up and realize you want to be together forever.
At first, it doesn't look too hopeful, but years later, you encounter the book and $5 bill, proving there is nothing keeping you apart.
You'll start messaging each other, somehow never realizing how physically close you actually are.
First you bump into each other while Christmas shopping.
Then you exchange numbers (one written in a book, the other on a dollar bill), deciding to leave everything up to fate.
However, your feelings soon take over, giving you a beautiful outcome you never expected.
Your parent will hire them to work for them, meaning they'll be around all the time. You used some fancy futuristic technology to erase your memories after a bad breakup, but you eventually decide to start over and try being together again, despite being polar opposites.
You'll work together, until one of your visas expires and, in order for the person whose visa expired to stay in the country, you get married.
