In modern cities, blessings, wishes, and promises that people casually say or send can gather into wish spirits if they go unfulfilled past their deadline, are forgotten, or are left with regrets. If wish spirits go uncomforted for too long, they become twisted and turn into Rule Horrors, transforming real-world areas into deadly instances that trap the living. Anyone who breaks the rules dies on the spot.
Ordinary people cannot see wish spirits or the rules of these horrors, leaving them helpless when caught in a crisis. Only Hosts of wish power can see expired blessings, purify wish spirits, break Rule Horror rules with wish power, and rescue those trapped inside.
The core of a horror's birth is the resentment built up from unfulfilled feelings, not simple malice. The key to breaking through is to make up for regrets and dispel resentment, not to kill.
The female lead can see the written form, expiration date, and regret value of every blessing. She can recover expired blessings with her bare hands and purify them into pure white wish power by reciting a blessing and empathizing with the regret behind it. Wish power can directly tear apart Rule Horror rules, soothe vengeful spirits, and open a path to survival. The more heartfelt the blessing and the deeper the regret, the stronger the wish power.
