Yan Zhiqing heaved a sigh of relief.
"They didn't expect me to be home. I was supposed to be rehearsing a play, but it got canceled last minute so I went home instead. I was so mad when I heard their conversation. I wanted to expose them, but I couldn't do so without evidence, so I recorded their conversation with my phone. The more I heard, the angrier I got with their words. I couldn't help it and kicked the door open. They knew I heard everything, so they gave chase. They wanted me to keep it a secret, but I refused. When I got into a tussle with my mum at the staircase, I fell down the stairs," Yan Zhiqing said as she lowered her eyes to look at her hand. She was feeling remorseful.
