Goodbye, one day behind the scenes.

The scene in which director John H. Lee spent the greatest effort was the moment when 25 years passed, and Feng in the scene changed from a young man to a middle-aged man in a flash. The Oriental Hotel in Bangkok, Thailand is an important location for the film. After the producer's negotiation, the hotel made an exception and agreed to let the film crew shoot in the store. In order not to affect the image of the hotel, all the staff were dressed in formal clothes when filming. More than 9% of the clothes Miho Nakayama wore in the film were specially made. There are more than 2 drafts of costume design. The original plan was to shoot the middle-aged part of the protagonist first and then the young part. In order to approach the role in appearance, Hidetoshi Nishijima gained 13 kilograms specially. Unexpectedly, the plan was temporarily overturned and the shooting order was changed. Nishima had to lose weight quickly again, losing fifteen kilograms in a month. Hidetoshi Nishijima revealed that director John H. Lee is a perfectionist. He once spent 3 hours in continuous shooting with special makeup, and the makeup artist once stated that continuous shooting's ten hours was the limit, and John H. Lee was able to shrug off it. The film was filmed on location in Thailand and Japan, and some interior scenes were filmed in the studio in South Korea. The filming process lasted for one year. The working team is mainly Koreans, supplemented by local filmmakers on location. Korean directors, Japanese actors, and multinational staff made up the shooting scene of Korean, Japanese, Thai and English, which was very lively. Miho Nakayama's husband, Hitonari Tsuji, is the original author of the film. He was unfortunately injured in the head in an accident in October 29. When he returned to his hometown of Fukuoka, he was even more paralyzed. Finally, he had to call an ambulance to be sent to hospital for treatment. On January 2, 21, Hitonari Tsuji operated to remove blood stasis in his head.
