Gao Yang lightly coughed and said in a deep voice, "It's all in the past."
Number Thirteen, with a serious face, said, "It's not over."
Gao Yang softly said, "It can be, it really can be."
"The things that aren't over, you don't understand."
"I understand. It really can be over. As long as you try to accept a new life, everything will pass, and the future will be better."
Number Thirteen smiled faintly, shook his head again and said, "No, it won't be over."
