In a world where malevolent spirits roam freely, Jeong Wol has spent his entire life pretending not to see them. Having witnessed countless evil entities since childhood, he believes that ignoring the supernatural is the only way to survive. That fragile resolve shatters when he becomes entangled in a mission led by the Disaster Squad and loses his life in the process. Or so he believes. Jeong Wol awakens to find himself alive once more, bound by a mysterious pact with Sa Hyeon, a black serpent whose presence radiates both danger and allure. Granted immortality in exchange for an unknown price, he is forced to confront the very world he tried so desperately to deny. Is this second life a blessing that spared him from death, or a curse that will drag him deeper into the serpent’s shadow?
