"Back then, you weren't confident about Sisi either, right?" She finally spoke, her voice gentle, as if asking a question she already knew the answer to.
Yang Ping opened his eyes, looking at the ceiling light. The light was soft, like a small crescent moon, hanging in their shared sky.
"Yes, not confident," he said. "The human application of K Therapy was the first time; I honestly didn't know if it could work. But saying 'won't' at that time, she might not have made it through. A nine-year-old child, her eyes were already somewhat unfocused. Telling her about data, about probabilities, she couldn't understand or absorb it. What she needed was a definite answer, even if I had to make it up."
"What about now?" Xiao Su asked, "That sixteen-year-old boy, why don't you give him a definite answer too?"
Yang Ping turned his head to look at her. Her eyes were bright under the light, as if encouraging him, or perhaps reminding him.
"Because it's different now," he said.
