Almost at the same moment, the door was pushed open a crack, and Shen Qingyu's clear voice came from inside: "Sister? Are you in the room?"

Meng Zhaoqiang calmly cleared his throat: "Yes, come in."

Having received permission, the brother and sister immediately pushed open the door and entered. But as soon as they crossed the threshold, they saw their second brother, dressed in official robes, sitting upright in a chair with a gloomy expression. His cold eyes swept over them, and the two of them froze on the spot like little quails with their necks being choked.

Shen Qinghe narrowed his eyes, his slender fingers tapping lightly on the armrest, his voice authoritative without being angry, "You two, where have you thrown away all the manners you learned since elementary school? Who taught you not to knock before entering?"

The two were startled; they hadn't seen their second brother so angry in a long time. They quickly lowered their heads and admitted their mistake: "We're sorry, second brother, we were reckless."

"Are you going to apologize to me?" Shen Qinghe raised an eyebrow.

The two turned to Meng Zhao and bowed respectfully: "Sister, we were impolite just now. We shouldn't have barged in without knocking."

Meng Zhao was also startled, but considering that her study was usually kept open and they were used to coming and going, it was understandable. However, the current situation was special, so she nodded slightly, "Then remember next time, no matter whose room you go to, whether it's a study or a bedroom, you must knock first and get permission before entering."

The two nodded obediently, but their eyes glanced at Shen Qinghe to the side, seemingly wondering why their second brother was here and why his face was so gloomy. They began to wonder if he had made some mistake again and been caught red-handed.
