Can a fake start lead to a real future?

Kerwin is training to be a council assassin against his mother's wishes, but then he does a lot of things against his mother's wishes. The only thing she wants for him is to marry a nice demon woman and have lots of demon babies, so when he finds himself on a surprise blind date she organized, he grabs the first cute guy he finds and tells his date he has a boyfriend.

Fergus was at the coffee shop to meet his best friend, not to play fake boyfriend-to his mate? When Kerwin leaves, Fergus panics because he hasn't had the time to tell him they're fated to be together, but luckily for him, his best friend knows exactly who Kerwin is. Their problems aren't over, though.

Fergus and Kerwin are just starting to work things out when Fergus's sister gives birth to a half-demon baby she doesn't want. Fergus can't abandon his nephew, but he also can't be sure that Kerwin is ready to be not only a mate but also a father. Will he have to choose between being the two?
