In a world where emotional spirits manifest as physical hearts, players assume the role of a Heart Collector, a rogue spirit tasked with navigating the tumultuous realm of souls to retrieve hearts from those plagued by emotional turmoil. Each heart has its own story and challenges. Players must engage with the heart's owner, unfold their narratives, and decide whether to help them mend their broken emotions or selfishly seize their heart for power. Choices affect the narrative trajectory, relationships, and the nature of the Collector's own heart, leading to multiple, intricate endings based on the player's moral decisions.
