From MangaCity:

Redrum 327, a manhwa by Ko Ya Sung, plunges readers into a world that's a cross between the "Scream" franchise and Stephen King's "The Shining." It tells the tale of a group of friends who plan an impromptu visit to an isolated chalet in the mountains. Their weekend getaway starts out as a pleasant idyll, but as the evening progresses, tensions rise, rifts form and conflicts occur. Soon they start to experience strange disappearances and hallucinations, and that's when their trip turns into a real nightmare.
