With one last effort, Zhao jumps out the window, protecting the girl he carries with his body. While he faints, despite the pain of the glass cuts and hits, he is at peace because he rescued her from the fire and death. 

His mind travels to the day when the most beautiful person he had ever seen stole his heart with a smile. Then, he wakes up in the ambulance with the girl. She whispers, crying, "Grandma." The paramedic shrugs, "We save more lives since vasopressin can be injected using nanobots during CPR maneuvers." Zhao simply states, "It's love."
