Ding Jiayi wasn't young anymore. However, in this lifetime, she had never dealt with any serious matters independently before. When she was young, she relied on Qiao Dongliang. When Qiao Nan grew up, Ding Jiayi would push all the important matters to her. When these two people weren't by Ding Jiayi's side, Ding Jiayi panicked.
Thankfully, Ding Jiayi's brain was still working. Indeed, she couldn't contact Qiao Dongliang. However, she should be able to contact Qiao Nan. Without Qiao Nan's help, she, who had 'lost' her identity card, wouldn't have been able to return to Ping Cheng.
Upon thinking about this situation, Ding Jiayi felt that Qiao Nan wouldn't ignore her. Furthermore, she was approaching Qiao Nan this time around not to find her trouble or for herself. Qiao Dongliang was her man and Qiao Nan's biological father. Old Qiao was missing. As Old Qiao's biological daughter, shouldn't Qiao Nan care about Old Qiao's situation?
