Lu Yinchu's arrival wasn't unexpected.
He was feeling a bit upset last night, so he decided to go back to the Lu Family residence. The old man was asleep, yet Xia Zhen was still awake. As soon as he arrived, she rushed over to greet him and had his mother bring over a sleep aid soup they had prepared earlier.
Lu Yinchu could tell that Xia Zhen had been waiting for him that evening.
After drinking the sleep aid soup and calming his emotions, he waited for Xia Zhen to ask her questions. Not wanting to delay her son's rest, she simply told everything as it was.
During the day, after Li Mufang had dealt with her brother Li Weihuan's fight, she did not return directly home. Instead, she went to the Lu Family residence, where she had dinner with the old man before returning. But the moment she stepped out of the Lu Family gate, she was stopped by Qi Qun!
