At Gu Yiye's wedding, Gu Yiye told Xiao Fei that he would work hard to be a good father. Xiao Fei yelled that you are not my father, Zhang Fei is. At the wedding scene, mentioning the past that had been dusted for many years, did you know that this was the pain in Gu Yi's ambition? It was really inappropriate to rub his benefactor's heart and slap his face on the big day.
