We met at the beginning of thirteen years old. When she was fifteen, she said, "Gu Siming, I don't seem to hate you that much." When she was sixteen, Gu Siming blocked a knife for her. At the age of seventeen, she said, "Gu Siming, I like you." He thought about it for a long time and gently hugged her into his arms. They went through the happiest five years, but in the end they couldn't beat reality.
