In a world where Fate decides who grows horns and who grows a tail, Juro fails his classification when he lacks the aggression that should have come with his horns.

Divorced in his mid-twenties, with a child to raise and an ex-spouse extorting Juro for money, the last thing he's looking for is another relationship. His failed marriage proved that Fate dealt Juro a cruel hand, and the passion and aggression expected from a horned man simply don’t exist inside him.

When Shig, the tailed guardian of a troubled student, steps into Juro’s life, the unexpected friendship that sparks between the two single parents is put at risk when Shig makes it clear he wants more. Juro believes he’s broken when it comes to love, and failing another partner could destroy him.

After tragedy strikes, Juro’s given a once-in-a-lifetime chance to discover if he and Shig can find happiness together, but his ex-spouse is determined to ruin Juro’s life. Can Juro and Shig risk it all to discover if they're Fated mates, or will the mess from Juro’s past be too much for their budding relationship to endure?
