In a not-so-distant future, a quirky scientist offers a unique experience: the ability to swap emotional hearts with others for a day. As the protagonist, you navigate a world where emotions are shared, and connections are deeper yet more complex. Each choice you make leads you into dramatic encounters with individuals from all walks of life—each heart revealing its own secrets and struggles. Will you grow to understand love from a lover's viewpoint, anguish from a heartbreaker's perspective, or ambition from a ruthless CEO's heart? As you piece together the true nature of happiness, be prepared for mind-bending twists that challenge your morals. Keep your wits about you, or you might just lose your own heart in the process.
