"Why is it me? You started attacking me first."
"Me? Mom and Dad, why don't you ask Sis, who really started it."
...
The two were still putting on an act, preparing to make it seem even more realistic.
Jiang Chengsi had a headache, glanced at Si Qingxiao, and asked her how to resolve the situation.
He's usually able to mix with the kids like friends, so basically, Si Qingxiao handles the education issues at home.
Si Qingxiao simply observed the two brothers. Their little tricks couldn't fool her, but she didn't expose them, "You're home now and still arguing? Don't you find it embarrassing?"
The two simultaneously fell silent.
"You're so grown up now and still fighting outside. We really should find an opportunity to help you develop a better brotherly bond."
...
Si Qingxiao's way of cultivating brotherly love meant that the next day, the two brothers appeared at home holding hands.
And not just holding hands, but fingers intertwined.
