Zhu Mingzhan did not think Song Yujin was lying, but he was unwilling to accept it. So, he continued to coax, "Why was Lu Suo the only person who went to save Zhu Yi? No one else noticed?"
"When Lu Suo went to the bathroom, he heard the sound. That's how he found out," said Song Yujin.
Zhu Mingzhan quickly asked, "How did you know? Did Lu Suo teach you to say these words?"
"I saw it."
Song Yujin's voice was cold.
"When you guys left, the other children bullied Little Suo. After that, Little Suo went to the bathroom. I was worried he might be bullied again, so I followed him. That's how I saw everything."
Lu Gan looked at Song Yujin.
"Who bullied him? What did they do?"
Song Yujin replied, "They said a lot of unpleasant things to Little Suo,"
"Like what?"
Lu Gan pressed.
Lu Suo quickly shouted, "Song Yujin, don't say it!"
