At the End of Death

Death is just the beginning for Gwon Jun. After committing suicide, he doesn't find himself in the afterlife but rather, in a cold, surgical room. He's strapped to a table and there's a figure staring down at him. Is this the person who saved his life? But why? Jun is not dead but he's not exactly alive either... This strange state of being that Jun is in seems to be a part of some sort of research being done by the mysterious man who saved him. As the two of them live together in isolation, they both seem to be discovering odd things about each other. But eventually, something's gotta give and the truth will be revealed. What answers will be found at the end of death...?
