Richard, a broke, sharp-tongued black-market vet, gets evicted from his rundown flat and is hired at an astronomical rate by the mysterious noblewoman Catherine to be the night keeper of Ashford Manor. His plan is simple: coast through the shift, collect his paycheck, and get out. But when he stumbles into a forbidden zone to save a mortally wounded Abyssal Royal Squid, he inadvertently completes the seal on an S-class calamity—and the overflow magic floods straight into him. Suddenly, the entire world thinks some legendary hidden powerhouse just obliterated the disaster. He keeps healing beasts for the money, but the more he heals, the stronger he becomes, earning him an A-rank agent badge from the DMTC. As he digs deeper into the manor's secrets, he uncovers the horrifying truth—this is no mansion, but a crumbling prison built on the souls of fourteen ancestral guardians, barely containing thousands of calamities. And he has been chosen as the sole heir to inherit their power and end a century-long nightmare.

I was slowly dying from Silverthorn Wolfsbane, and there was only one cure—the Miracle Elixir. But my mate, Leo Ashford, bought it and gave it to my adoptive sister, Jane Smith. He did it because he thought I was faking my illness. I gave up on the treatment and swallowed a potent painkiller instead. It would kill me in three days by shutting down my organs. In those three days, I gave up everything. I handed over the fur manufacturing business I built from the ground up to Jane, and my parents praised me for caring about my sister. I offered to sever our mate bond, and Leo praised me for finally being sensible. When I told my son he could call Jane "mommy", he happily said that his new mommy was the best! I transferred all my savings to Jane, and no one seemed to notice anything out of the ordinary. They were just pleased with my "better behavior". "Viola is finally not so bad." I wondered—would they regret it after I was gone?
