In a near-future society where people's hearts can be literally swapped, players assume the role of a 'Heart Broker' tasked with managing the heart trades of emotionally unstable clients. As you navigate through a series of complex ethical dilemmas, dramatic encounters, and unexpected twists, you must choose hearts for your clients based on their emotional needs, historical baggage, and compatibility. Each heart carries its own memories and feelings, affecting both the broker's life and those of the clients. Your choices will lead to various outcomes and determine whether you become a hailed healer or a notorious heartbreaker.
