Once known as a talented consultant, Kwon Hae-eon has fallen into disgrace, struggling to maintain his reputation after losing his unique skills nine years ago. His life takes a sharp turn when Moon Woojin, a man suffering from an unknown and aggressive condition, suddenly appears. Curiously, the moment they make contact, Hae-eon feels his long-lost abilities mysteriously returning.
Woojin, plagued by misfortune and with nowhere else to go, ends up staying at Hae-eon’s private residence. Every night, under the influence of his condition, Woojin undergoes an intense physical reaction that requires Hae-eon’s constant intervention. The next morning, Woojin wakes up with no memory of the night’s events—only the lingering exhaustion he cannot explain.
For Moon Woojin, a man of deep faith who has always lived an upright life, the realization that he is sharing such intimate and inexplicable nights with another man feels like a divine test.
"How much further can I fall? Why am I being tested in this way...?"
