Qi Taiguo's outburst was triggered by Qi Xiaoqi's words. Today, he saw Mother Qi give Cheng Su several looks, and he didn't want Cheng Su to have to mind his mother's expressions after he left. Even if Cheng Su couldn't read her expressions, over time, it would still hurt their relationship.
Therefore, having his mother-in-law take care of Xiao Qi to avoid long-term interactions between the mother-in-law and daughter-in-law was the right choice. Getting along is easy, but living together is hard. He didn't want his mother to make a fool of herself from time to time, making things awkward.
For everyone's comfort and ease, it's good to take turns this way.
"You should have told me earlier." Cheng Su said to Qi Taiguo in the room, "I didn't really know how to react all of a sudden."
"It's not too late to say now. I also just told my mother-in-law this morning," Qi Taiguo said. "You also didn't tell me about the foolish things my mom did before, like the Talisman Water."
