The World's Most Dangerous Sleepwalker

Sung Jinwoo has sleepwalked since childhood, a habit that worsens after losing his parents and becoming Korea's weakest hunter. Surviving the Double Dungeon awakens the System within him-and as he grows stronger, his sleepwalking evolves into a dangerous ability that sends him into dungeons, S-Rank homes, and even foreign territories without waking. Korea's and then the world's strongest hunters scramble to handle the "international sleepwalking crisis" caused by the newly risen S-Rank who has no idea where he'll wake up next. Amid the chaos, Cha Hae-In becomes the one person he unconsciously gravitates toward, sensing the fear and loneliness beneath his wandering. With her support-and the people who care for him-Jinwoo finally finds a place where he can rest without walking away.
