Fredric has found his mate, but he's completely perplexed. His mate is not only a man, but also a half-demon. Fredric cannot believe the gods have done this to him. On top of this odd turn of events, Fredric is suffering from the Dissolution, a vampire disease with no cure. He knows accepting Satoru as his mate and taking his blood increases his chances of survival, yet he keeps fighting his fate, even as Satoru becomes more appealing with each encounter.
Satoru refuses to give up, and with each passing day, Fredric becomes less resistant. Fredric first agrees to drink Satoru's blood, and then he accepts Satoru as a lover. But as time runs out and other troubles come, will Satoru be able to save his lover's life and truly win his heart?
