That evening five years ago, when Chu Yan knelt down on one knee and handed the ring to Xia Cheng, she was in great grief over the death of her best friend. There was only gray rain left in the world, and she didn't even hear his confession clearly. She just turned around and ran away, leaving the words "I do" and the light in his eyes behind.
She didn't know that Chu Yan's already fragile heart suddenly stopped the moment she turned around. For three days and three nights outside the rescue room, the red light was dazzling. In the end, the doctor defined his survival as a "miracle", but it also left behind more serious hidden dangers.
Not long after, Xia Cheng discovered that there was a little life in her belly - that was the only connection between her and Chu Yan. With unspoken apologies and confusion, she quietly left City A and returned to her hometown, leaving all the past behind.
Five years passed, and she thought her life had long since returned to peace, but she unexpectedly bumped into that familiar yet unfamiliar figure in the coffee shop on the corner of the street. Chu Yan's eyes fell on her, and also on the face of the little boy next to him, whose features resembled his own.
The unfinished confession, the late explanation, the secret that had been hidden for five years, and the heart that had stopped beating for her, at this moment of reunion, the belated answer was finally coming.
