In a world where emotions can be swapped like currency, you play as a 'Heartbinder'—an eccentric artisan who crafts emotional connections between people. Trapped in a bustling metropolis where individuals are emotionally disconnected, you must navigate a web of relationships, trade hearts for favors, and solve convoluted emotional dilemmas. Each choice you make affects not only your own emotional state but also the lives of those around you. Can you restore genuine feeling to a city turned cold, or will you become just another heartless merchant in the end?
