In a world where emotions can be physically manifested, you are a 'Heart Harvester' tasked with exploring the city's hidden emotional districts. As you navigate dark alleys shaped by unresolved feelings and obsession, you encounter characters each with a unique heart (literally) that embodies their deepest yearnings. Players must engage in witty conversations, moral dilemmas, and mini-games to collect hearts while unraveling the mystery of the Heart Thief—a rogue mastermind who is stealing the essence of emotions from the very fabric of society. Every choice alters the relationships you build, unlocking new branches of the story as you hunt for the truth behind your own missing heart.
