In a world where emotions are physical entities, you are a Heart Collector, tasked with gathering and trading the hearts of people from different regions. Each heart embodies specific traits—courage, sorrow, love, and more—that influence the world around you. As you interact with various characters, you must make choices that affect their emotional states and your inventory. Navigate complex relationships, solve emotional puzzles, and determine whose heart you truly want to hold onto. But beware—the hearts you choose to collect might have unforeseen consequences, leading to dramatic twists and unexpected character developments.
