Set in a bustling, surreal city where human emotions can be traded as physical currency, players step into the shoes of an emotionally-bereft detective who wakes up with no memory and a heart missing. As they navigate through the city's vibrant underbelly, players uncover a web of intrigue involving emotional black markets, heartless syndicates, and quirky characters with their own agendas. Players must interact with eccentric NPCs to gather clues, uncover the truth about their identity, and ultimately face the chilling question: who has taken your heart, and why? Choices made during dialogue shape the detective’s emotional landscape, leading to multiple endings based on whether they can reclaim their heart or embrace being heartless.
