You and eight other friends were being disturbed by something. What was this thing? An entity? A killer? You had no idea what that being was, but you knew it was extremely dangerous. Each of you was having scary experiences with this being that was chasing you, adapting according to your fears. It had the ability to simply transform whenever it wanted.

You gathered in Taeyong's garage, one of your friends who was also frequently disturbed by the being. He reported seeing his little brother, who had died a year ago when he supposedly fell into a sewer, and his body was never found. The projector you used to view the map started malfunctioning, displaying strange photos... Until in one of them, you saw it, the thing in its natural form, that of a clown. Johnny turned off the projector and opened the garage door, making the clown disappear when the sunlight entered the room. You all sighed in relief, except for Taeyong. The boy grabbed his bike and hurried to the abandoned house, the place where Haechan was also haunted by the clown.

You hurried to go after him and stop him from entering the abandoned house, but he was determined to go in and try to face whatever was inside. He couldn't stand being haunted by his own brother anymore, to be clearer, by an evil being that used his brother's image to haunt him. After a brief discussion about who would stay outside the house, you concluded that you would all go in together.
