Step into the shoes of Kai, an emotionally detached heart transplant surgeon who discovers a hidden talent for 'phantom empathy'—the ability to feel the emotions and desires of the donor's loved ones. As you navigate a series of dramatic cases, you must make tough moral choices while unraveling the backstories of the hearts you operate on. Will you follow the logic of medicine or the chaos of human emotion? With each choice you make, relationships fracture or bloom, lives change, and secrets unveil beneath the surgical masks. Every story reveals something deeper, and you must decide if the patient truly deserves that second chance.
