Even though Su Zheng wasn't as devastated as Kong Yue, his already red eyes and his face full of regret and self-blame showed his pain.
He recalled how he looked like he didn't care when Su Qing's hand was pierced by a flower thorn and she didn't stop bleeding for a long time. He wanted to slap himself fiercely!
When he saw Kong Yue's nervous look at that time, he even mocked her. Thinking about it now, he really shouldn't have.
Kong Yue was right about one thing. Su Qing could have avoided this disaster. As long as they cared a bit more at that time and discovered this huge hidden danger in time, with prevention and early intervention, all of this might not have happened!
However, the consequences were already set in stone. No matter how much regret and self-blame there was, it was useless.
