New Orleans firefighter, Caleb Moureu had to trade body shots and hot all-nighters for sippy cups and actual up-all-night fevers when his sister was killed, leaving his niece in his care. But two years in, he’s definitely got the hang of this fatherhood thing. Of course, he couldn’t do it without nanny-turned-friend and fellow single parent, Lexi. Because of her, things have always been pretty easy.

Getting pregnant and going it alone wasn’t in Lexi’s plans, but thanks to Caleb, she’s doing okay. He’s helped her out with everything from diapers to car repairs over the years. So, when she suddenly needs a place to live, of course Caleb steps up. After all, it’s only temporary. They’re just friends. It’s just a favor, like all the others.

But for now it really is, very, very nice.
