Part-Time Grim Reaper

Story:

"Lee Do-jin desperately needs money—a vast sum—to pay for his younger sibling's medical treatment. With no other options, he dials a number from an eerie, unsettling business card he stumbles upon. At the meeting spot, he comes face-to-face with a mysterious silver-haired woman—a reaper of souls, called a Chasa. She presents him with an astonishing proposal: become a temporary employee of the Underworld. His task? Hunt down “Mokdugi,” creatures that prey on corrupted souls, preventing them from devouring the damned and unleashing chaos. Plunged into a world of death, debt, and supernatural conflict, Do-jin must juggle his humanity while working a job that forces him to straddle the boundary between the living and the dead."
