In a world where emotions manifest as physical entities, you play as an Emotion Collector, responsible for tracking down wayward hearts that have escaped from their owners. Each heart you encounter presents a unique story—some are joyful, others are desperate, and a few are downright vengeful. You must navigate a labyrinth of memories and choices, interacting with both human and heart characters to solve their dilemmas and restore balance. The stakes increase as you uncover a dark conspiracy leading to the Heart Factory, a place rumored to be harvesting emotions for sinister purposes. Your choices will determine who gets their heart back and whether you'll survive the trials of this emotional rollercoaster.
