If Zhao Yu didn't know about Xu Meng Lan's attempted to poison him, he might think she was used to being abused.
But now, she likely wanted to delay time, fearing that Zhao Yu would take action against her younger sister.
Zhao Yu shook his head and helped Xu Meng Lan up. "I'm tired, let's leave it for now."
Promising not to abuse her anymore would sound hollow now. A year had passed, and people don't changed over night. All he could do was gradually change their perceptions.
Xu Meng Lan stood still, her expression fluctuating, seemingly guessing whether Zhao Yu was genuinely tired or had ulterior motives.
She signaled to Xu Xiu Lan, who was watching from a distance.
Xu Xiu Lan quickly got up and quietly approached the door of the youngest sister's room, knocking in a pattern of three long and one short knock.
