The purpose of this study was to examine the effect of relationship between dark tourism storytelling, love marks from tourism, and intention of action : the mediating effect of tourism love marks. In addition, this study was proposed by the mediating effect of love mark on the relationship between dark tourism storytelling and intention of action. The empirical analysis was analyzed using the SPSS WIN Ver. 22.0 statistical package program after the questinnaire was collected, and the survey was conducted from January 20 to February 10 in 2021, and the survey method used a self-written online survey method targeting tourists who visited the DMZ in the past. A total of 181 questionnaire was collected. Looking at the analysis results, In summary of relationship between the storytelling, lovemarks and behavior intention behind Dark Tourism, ‘interest’ and ‘educational factors’ are likely to have greater impact on the creation of tourist’s lovemarks on the tourist sites, compared to other factors such as ‘comprehension’. It is attributable to the poor delivery of tour guides in sharing the history, or spatial constraints considering that the guide is provided outside. In order the overcome such constraints, the storyteller should pick plain words that are less ambiguous, and increased support should be provided such as competent staffs who are capable of grabbing visitors’ attention at all times and more sophisticated equipments like microphones. The study suggests that ‘reputation’, one of the factors behind lovemarks, having had little impact on ‘intention to revisit’ or ‘intention to recommend’is due to the visitor’s perception of DMZ, associating the place with death. In other words, the place itself has a somewhat negative image, which led to the visitors not recommending it to others. In order to address such difficulties, positive outcomes should be proven by promoting artistic or cultural advantages of historic sites, and holding musicals, plays or exhibitions of tragic history are all case in points. In the end, such endeavors could improve its overall image, providing opportunities to become proficient in history. As a result, interest in Dark Tourism, including visiting DMZ, would begin to grow if they are exposed more frequently in our daily lives, which means more recommendations and revisits would also take place. In addition to that, if the Dark Tourism were combined with a wide range of areas, rather than a single area, public awareness could be further improved.
