In a world where people can temporarily swap hearts, you play as Alex, a quirky detective tasked with unraveling a series of bizarre heart thefts across the city. With each heart swap, the personalities and memories of their owners also change, creating a web of confusion and mistrust. Players must interview suspects, solve puzzles, and navigate the emotional fallout of stolen hearts, all while planting humor and irony in their dialogue. Each choice affects the outcome of Alex's investigation and the fates of those whose hearts are in flux, leading to multiple endings based on empathy, betrayal, or even romantically rewriting one's past.
