“Someday, you’ll be on your knees begging.”
“Will I, though?”

Is this twisted fate a coincidence or destiny?

In the peaceful summer of his 23rd year, Hwiyeon’s life is shattered when his brother, possessed by a demon, attacks him. With his soul in a coma, the key to saving him and seeking revenge lies in a cryptic message from a Grim Reaper: “Find a living agwi and breathe life into its hands.”

Becoming a ghost-hunting YouTuber, Hwiyeon eventually finds the living agwi, Cheongyeol. Their rocky first encounter is filled with misunderstandings, but amidst suspicion, something strange begins to bloom.
