For as long as Alyssa Torres could remember, she and Kelly Severide had hated each other.

Neither of them could really remember a time where they weren't at each other's throats. They couldn't agree on a single thing but occasionally - just occasionally, they could work together without wanting to kill each other. But they could never imagine not hating each other.

But what happens when something that could change their entire relationship occurs? Will they still hate each other when everything is over?

A/N: I only own Alyssa Torres, the members of Firehouse 90, Alyssa's family, and everyone else not in the One Chicago TV series.
