Is it true that Fallon went to Weizi the next day?

No. When Wei Zi was killed by soldiers in the street, Erkang took Wei Zi to the bachelor's office. After a period of contact, both of them moved their hearts and wanted to be together. After seeing this situation, Fujin of Fallon went to talk to Wei Zi overnight, hoping that Wei Zi could understand her good intentions. The next morning, Wei Zi left the house with a golden lock. Fallon didn't find Wei Zi.
