Sinbi Apartment: Cheolgungiwa Cheolwon Hieolojeu Hantangangui Jeonseol

Cheolgoongi is kidnapped by the Hwansugwi, a ghostly creature that lures people before turning them into prey. The Cheorwon Heroes realize they cannot rescue him alone and seek out Hari and her friends, bringing the Haunted House team into a new mystery around the Hantangang River.

The rescue becomes more complicated when another unfamiliar being, Kkeokji, appears near the river. To save Cheolgoongi, the two groups must combine their knowledge and courage, uncover what the new creature really is, and confront the legend haunting Cheorwon before the ghost claims another victim.
