In a world where people's emotions are literally embodied in glowing hearts, you take on the role of a 'Heart Collector,' someone who travels through the lives of individuals, experiencing their deepest joys, sorrows, and regrets. Your mission is to collect enough hearts to save a mysteriously fading emotion—a critical feeling needed to keep the universe in balance. But beware! With every heart you collect, the emotions you embody seep into your soul, testing your own humanity and ethical compass. Make choices that shape not only your journey but also the lives of those you've met, leading to multiple endings that expose the fascinating complexities of emotional intimacy and moral dilemmas.
