While working late one night, Kang Hyuna died in a sudden explosion... or so she thought. She wakes up as Belita Olden, the villain in the game she developed, "The Guardian's Garden." Unfortunately for her, this character is destined to die at the end of each route for messing with the heroine, Margaret Averdeen. Determined not to die a second time, Belita decides to go against the game and help Margaret have a happy ending instead. Thus begins her journey for a second chance of her own making! (Source: Tapas)
