My Trash Pup Is Fenrir

Rayne, a enigmatic beast tamer who grew up in the mountains, comes back to the city with a scruffy stray dog named Max at his side. He reunites with Elena, the girl he vowed to marry fourteen years earlier, only to learn she is now betrothed to a wealthy nobleman. As raiders close in on her city, Rayne sets out to discover who he really is, stir the hidden strength within Max, and shield the woman he has never stopped loving.
