From Now On, No Return in Wind and Rain

From Now On, No Return in Wind and Rain Plot:

Emergency doctor Lin Wan waited three years for her firefighter boyfriend Gu Zhao's promise: "We'll get married after this mission." Until a typhoon rescue operation, she encountered Chen Mo, a rescue team leader who looked exactly like Gu Zhao. He said, "We've never met," but his ear scar, his seatbelt habit—all were details Lin Wan had etched into her soul. During a dangerous building rescue in the downpour, Chen Mo was hit by a beam while protecting Lin Wan. Before passing out, he finally revealed the truth: an explosion left him disfigured and amnesiac, so he hid his identity to avoid burdening her. What Lin Wan didn't know was that the stack of unsent letters in her drawer—each crumpled by rain, bearing the words "I'm waiting for you, no matter the storm"—had long been secretly taken by Chen Mo.
