An EVIL SPIRIT in Seoul?! True Nightmares from History

#1 JUNGWON’s Case A cave in Utah, infamous for its narrow, twisting labyrinths, reopens after being closed to the public for 40 years,. John sets out to explore the cave. When he was about to turn back, his friend whispers: "The real highlight hasn't even started yet." Driven by curiosity, John ventures deeper. #2 SUNOO’s Case A chilling mystery that terrorized Joseon, a Korean kingdom, in 1637. Whenever the rain fell for days on end, people died in their sleep, paralyzed by fear with their eyes wide open. No evidence, no traces left behind. Except for one spine-chilling detail from the neighbors: the night before they died, a strange, phantom "hwehwe" sound was heard. #3 NI-KI’s Case “Looking for Lucia Scarlett.” In 2006, a post appeared on an American online forum searching for a mysterious author who had left behind only a name and a single mystery novel. Then, a comment reveals that she was the “Queen of Mystery Novels,” a literary figure who took 19th-century Europe by storm.
