When Wu Bai came to Ai Qing's house, Ai's father greeted him to sit in the living room, but Ai Qing said that something happened and took Wu Bai into the room. She heard Wu Bai talk about the wedding next month, and she was very anxious that she was still not ready for anything. Wu Bai told her that grandpa said that this happened just in time for the National Day. Ai Qing said that they hadn't received the marriage certificate yet, but Wu Bai had already prepared. He took the certificate with him and said that he would do it in a while. The two of them walked out of the room but found that their father and sister were eavesdropping. Hearing that they were going to get the certificate, the father had already prepared and gave the account book that he took with him to Ai Qing.
