Married

That boy and girl. 
That aren't quite best friends.
But they tell each other almost everything.
When they're in public, they follow each other around, and don't leave each other's sides.
They always say that they don't have feelings for one another. 
But they're constantly hoping the other does.
When they hang out, they just laugh.
Everyone who doesn't know then asks: 
"Are you two dating?"
They smirk, and reply polietly, "no."
They wish they were though, 
Everyone thinks they should too. 
They always fight, 
But nothing too serious. 
They need to get married
