In ancient times, Mayoiga was considered a mystical location that granted great rewards to those who journeyed through the mountains. Currently, this enchanting spot can be found within a maid cafe. Natsuki, one of the staff members at this establishment, discovered not wealth or renown but rather the affection and enjoyment she experienced from a young admirer named Isami. Recently, Isami sent Natsuki a heartfelt message, prompting him to visit her at the cafe. However, Natsuki's coworker Akiha quickly developed feelings for Isami and unexpectedly emerged as her rival for his affections.
