There was a boy who loved a girl very much and cherished her like a treasure. When it rained, the boy always tried to hold the umbrella over the girl, getting himself wet but still smiling sweetly. The girl was very touched and also liked the way the boy pampered her. One day, after they went for a walk, they passed a construction site and suddenly a piece of broken stone fell from above. The boy hurriedly used his body to shield the girl, but suddenly he turned the girl around onto his back and fell to the ground himself. The girl fell heavily on him, and the stone hit her forehead precisely, blood slowly flowing out. The girl ran home crying; she was really disappointed. The boy called her many times, but she didn't answer and turned off her phone, locking herself in her room and crying. She was only awakened by a knock on the door, and her mother told her that the boy had been pierced through the lung by a steel rod and had died from excessive blood loss. She ran to the hospital like a madwoman; the boy lay on a white hospital bed, tightly holding his phone, which had this message written on it: 'Darling, when I saw the steel rod on the ground, I could no longer shield you from the stone. Darling, does it hurt?' The girl held the boy's body and cried bitterly. Cherish the person you love; don't wait until you lose them to realize it.
