The producer said that in the script writing stage, the expected heroine is Serina Liu. This film is the second time that Liu Zhen plays a couple with Li Minji after the TV series Really Really Like You. Liu is really a hothead. On one occasion, her opponent almost got angry because of his different understanding of the deductive method, but Li Minji was very gentle and always patiently communicated with her, so that Serina Liu gradually calmed down. Li Xiujing is a huge fan of the leading actor Li Shanjun, so when he first met each other on the set, he was a little at a loss. Li Shanjun said that Li Xiujing was the actress with the least ng times during filming. Liu Zhen was invited as the Philippine tourism ambassador to shoot this film.
