"White Day", a horror adventure game that has gone down in the history of the Korean gaming industry, is not a cruel horror game with hideous monsters and spooky mood, but a Korean-style horror game with auditory effects of ghastly sound. This paper aims at identifying the positive story-telling structure through the components of the game. This study found that the game is based on a well-organized scenario by the background, events and characters. In addition, its design and story-telling structure turned out to reinforce the positive effects of the game, by not imitating the western-style splatter games. As it provides players with playful components that bear mimicry and ilinx to maximize interactive fun, White Day is a prime example of positive games that are strongly needed in this era.
