Sa Hyun, a renowned hunter from the world's top guild, HN, expressed his interest in scouting Jeong Yi-Seon during his visit. However, Yi-Seon promptly declined and asked Sa Hyun to stop tailing him. In response, Sa Hyun chuckled, seemingly unfazed by Yi-Seon's refusal, and proposed a contract. Although Yi-Seon was uninterested, Sa Hyun offered to handle the bodies that were plaguing him. Despite his amiable disposition, Sa Hyun's icy gaze gave Yi-Seon an uneasy sensation. It's important to note that "A Trace of the Wonder," the official English title of the Korean novel, is rated R15.
