In a dystopian society where emotions are traded as currency, players assume the role of a heart merchant who has recently acquired a mysterious, sentient heart with the ability to manipulate emotions. Unbeknownst to everyone, this heart was tied to a powerful figure's tragic past, and now various factions are after it—each with their own motives. As players navigate through a city of shadows and secrets, they'll encounter a range of bizarre characters: from opportunistic emotion thieves to deep-web marketeers of feelings. Decisions made will affect the heart's behavior and the emotional landscape of the entire city. Will you trade the heart for riches, or pursue a deeper connection with the emotions it can evoke? Your choices will either save or doom the city’s inhabitants.
