On her eighteenth birthday, Lu Miao received a letter from the future, written by herself. There was only one sentence in the letter: "Don't marry Gu Ye." She was confused. Who was Gu Ye? She didn't recognize him at all. On the first day of college, she was almost hit by a car at the school gate, and a boy pulled her up. He said, "My name is Gu Ye. Are you okay?" Lu Miao looked at his face and thought to herself: It's over, I have to go against my future self.
