In 'Whose Heart Is It, Anyway?', players step into the shoes of a heartbroken detective navigating through a surreal world where the hearts of individuals have been detached from their bodies. Each heart is experiencing its own emotional crisis, and only by communicating with these separated hearts can the player solve the mystery of who has stolen the most important heart of all—the Heart of Humanity. The player must engage in deep dialogues, make moral choices, and sift through emotional turmoil while racing against time before all hearts fade away forever.
