Qin Yun thought for a moment and said, "Then the whole story is very clear, but I don't know the order in which the nanny, the child, and the scumbag died. There are several possibilities. The female owner came back that day, ready to go upstairs to see the child, only to run into the sick child going downstairs. The child, in a delirious state, blurted out the truth and then fell to his death right before her eyes. After discovering his diary, she killed the nanny, then invited the scumbag to the house and killed him, eventually driving herself insane."
"There's another possibility: the nanny invited the scumbag over, also for revenge, but the female owner caught them and found out the nanny's true identity. The child, hearing the argument downstairs, dragged his sick body out to see what was happening, and in his weakened state, fell in front of the female owner. After knowing everything, the female owner killed the nanny and the scumbag and went mad herself."
