Blood on the wall

Hyunggeon, a painter who has recently achieved great success, finds himself in high demand. One day while working, he impulsively scribbles on the wall, hoping to spark some creative inspiration. To his surprise, his scribbles seem to have taken on a life of their own. As he grapples with this strange occurrence, he begins to wonder if it is connected to his recurring nightmares. Things become even more complex when a guest unexpectedly arrives at his studio.
