Su Zhiruan didn't understand.
But now, she had grasped a principle: whoever provoked her, she would retaliate. She certainly wouldn't allow herself to be at a disadvantage.
Ever since Su Zhiruan had talked back to Ning Fu, Ning Fu had gone out and didn't seem to be doing anything in particular, until at one in the morning, Ning Fu hurriedly pushed open the front door and came back.
The noise she made was so loud that it woke up Su Zhiruan on the first floor. After turning over in bed, Su Zhiruan found herself unable to sleep again and picked up her phone to carefully listen to the commotion.
However, in the end, she didn't hear any useful information, only Ning Fu cursing a few times before there was no more to follow.
Su Qin indeed hadn't come back all night. As Su Zhiruan had guessed, Su Qin had probably spent the night out with his beautiful secretary, Ms. Zhu.
