Manseongjong

Manseongjong, individuals with the ability to hunt mutated creatures, are suddenly isolated in Narakga. Seoun, known for exceptional combat skills and considered a top-tier hunter, loses all abilities after being confined to Narakga. Instead, they gain the ability to sense mutated creatures through a 'messenger'. To escape Narakga, they need Ukwangseok, a byproduct of mutated creatures, but even a touch from one is fatal to Seoun. Cha Haya, upon learning the truth, proposes a deal: "From now on, Cha Seoun, you'll be my mutated creature informant." With Cha Haya's help, Seoun can travel to Seoul, but their situation becomes increasingly difficult. Seoun struggles with their growing attraction to Cha Haya, desperately trying to deny their feelings.
