Holographic viewing technology allows audience members to enter a movie and personally experience it for themselves. And if you succeed in altering the plot and pass a certain score, the cinema will re-release the movie with your character in for public view. Naturally, romance movies were the most popular and well-received, while nobody was interested in horror movies.
But not Su Min. He really likes horror movies and became the first customer to enter holographic viewing and become a side character to experience the whole plot. And to everyone's surprise, he succeeds in altering the whole plot and surviving until the end of the movie even when his character was actually written to be dead.
His first movie starts with his character summoning a ghost and the character does not manage to appease the soul and directly being killed by it. But when Su Min called for the ghost, the ghost that appeared seemed to be a bit pervert and even groped him while shooing him to bed.
Su Min started to doubt the identity of the said ghost when it appeared in every one of the movies he was in. Not to mention being a pervert in every movie and all the audience that saw the re-release was getting so hyped at the scene of the two of them, the ghost saves his character's life and leaving a confusing remark like a hint so many times which increased his doubt for his own memories.
