In a dystopian near-future, humanity has developed a technology that allows people to literally transfer their hearts to others, giving them a chance to experience life through different emotions and physical realities. Players take on the role of a heart 'broker' who travels between various factions in a city divided by wealth, power, and emotional control. As they navigate morally ambiguous choices and forge unexpected alliances, players must uncover the dark secrets behind the heart-stealing technology and determine who truly owns their heart. Each decision will affect the emotions and experiences they can share, leading to multiple, dynamic endings.
