The story centers on a secret, nightly market called Gwisi — a chilling place where ghosts are bought and sold. This hidden world is accessible only when a strange supernatural door called a “fox window” opens. People driven by deep desires — for money, beauty, grades, fame, or success — enter the market and make deals with spirits to get what they lack. But each trade carries a terrifying price, and as the characters dive deeper into the market’s bargains, their lives take disturbing, often horrifying turns.
