In a world where emotions can be harnessed and bottled, you play as a heart merchant in a bustling city where you collect and trade people's hearts instead of currency. Each heart has its own backstory and emotional energy, which can unlock special abilities or truths. Players navigate through intricate relationships with diverse characters, making choices that will either heal or harm them. With every heart you collect, you uncover dark conspiracies involving a powerful society that uses hearts for sinister purposes. As you delve deeper, you'll realize that you must confront your own feelings and the true meaning of connections.
