[This book is a slow burn, so please be patient.]
Roy, a doctor, meets a nun with a split personality. He performs surgery to save her, and from then on, both of her personalities cling to him.
"You saw it all, didn't you? Um... please take responsibility for me. I'll do my best to be a good wife."
"Doctor, now that you've seen everything, you have to take responsibility for me, okay?"
Meanwhile, all sorts of strange and dangerous things begin to appear: evil spirits, monsters in the swamp, an agent who transmigrated through time, a red hand in the fog, plague doctors...
Strangest of all, every time Roy dies, it seems to trigger a passive ability, and the more painfully he dies, the stronger he becomes.
As their fates intertwine amid endless chaos, where will the two of them, both hounded by darkness, end up?
