"I don't know what I will get in exchange for my eyes. But I will not regret the decision I made..."
Mu Qing used her eyes to get the chance to go back to the past again. Time was reversed, the future and the present were intertwined, and the trajectory changed.
"Are you willing to trade your eyes for a wish?"
"... Yes."
"Then, what is your wish?"
"I want... What do I want?... Then, let me live again..."
"When you wake up again, the deal is done. Your eyes will be kept by me. From now on, you will never see again. Are you sure?"
"What else do I have now? Nothing... Just a pair of eyes. What does it matter if you take them away? It's worth it to start over..."
"Okay, the deal is established."
