Rowan Calder is a paramedic who lives in a constant state of quiet exhaustion, driven by the need to save others because he once failed to save someone he loved. After losing his younger sister to an overdose, he dedicated his life to emergency work, answering every call as if timing alone could rewrite the past. Calm in chaos and deeply guarded in his personal life, Rowan is the kind of person who holds everyone else together while slowly falling apart himself — a healer who doesn’t believe he deserves to be healed.
