Meeting his mother-in-law was something Si Ning wasn't prepared for because he had already deduced it as them meeting after he had gotten married to Xiu Zhicheng but for her to suddenly show up at his residence was started to give him a headache he had to massaged his temples slowly while standing outside the meeting room door.
His father's meeting room was the best place for him to receive his visitors yet he wasn't able to calm his heart that kept skipping like he was about to face something unknown. According to Xiao Pei, it was just Song Ouyang and Queen Dowager in the room which means he had no problem recognizing her and it was a relief.
The problem was trying to think if they came to wish him quick recovery or if she came along to warn him to stay away from Xiu Zhicheng but he doubts that because if she was going to do so then she would have taken that action for a long time ago.
