In a world where emotions can be physically transferred between people, you take on the role of a cardiac surgeon who uncovers a clandestine black market for hearts with specific emotional traits. As patients arrive at your clinic, each with mysterious symptoms and tangled pasts, you must navigate a web of deceit, resolve their emotional crises, and ultimately choose whose heart to transplant—those that bring joy, anger, sorrow, or contentment. Your decisions will impact not only your patients' lives but also your reputation as an ethical doctor. As you unravel their stories, you'll engage in tense conversations, make heart-wrenching choices, and face the moral dilemmas of treating the human condition.
