Eight years ago, Fukamachi Naoya got lost in the Blue Lantern Festival and strangely met his deceased grandfather. Naoya, who is now a college student, developed the ability to understand people's lies since the day of the festival. When a person tells a lie, his voice is distorted and sounds strange. Parents who noticed Naoya's ability kept Naoya away, and Naoya also lived without having close relationships with others. However, Naoya is interested in Takatsuki Akira, a handsome associate professor whose words carry no lies at all. (Source: Tokai TV YouTube)
