What kind of story did an unsent text message record?

Boys and girls are a couple. Girls like to feel the rain. Boys always give umbrellas to girls when it rains. Most umbrellas are for girls, and every time the rain wets the boys' bodies. The boy said nothing, but silently looked at the girl's intoxicated face. He feels very happy, and so does the girl.

One day, a boy and a girl went to play. The boy took the girl's hand and happened to pass a construction site. The girl jumped up excitedly and said something. Boys rarely talk, just silently watching her happy, and they are happy. Just then, suddenly a small piece of gravel fell from upstairs and hit the girl's head. It's too late to hide The boy hugged the girl and the girl let out a scream. The boy tried to block the rubble with his own body, but just as he was about to land, he suddenly turned over and let his body face down. As a result, the girl's hand was broken by rubble.

The girl didn't react until she cried out in pain and shed tears. She thought that' husband and wife are birds in a forest, and when they are in trouble, they fly separately'. She fought back the pain and stood up from the boy. She ran away slowly without looking at the boy. At this time, the boy called the girl's name behind him, his voice trembled and his lips were white. He took out his mobile phone and dialed the girl's number, but the girl didn't answer. Dialed again, but she still didn't answer. After repeated several times, he gave up and just pressed something with his finger on his mobile phone. At this time, the blood slowly spread around the boy, his hand fell down and his mobile phone was lying in a pool of blood. He doesn't have the strength to press the send button.
