16, 15 On the morning of August, Tiffany posted her photos taken in Japan on instagram. Shortly after the photo was released, some fans pointed out that the words "Tokyo Japan" in the photo used the Japanese flag pattern. This day happens to be the day when South Korea commemorates its recovery from Japanese colonial rule. Therefore, many Korean netizens accused Tiffany of being thoughtless in publishing such photos today.

Although Tiffany immediately recognized the problem and deleted this photo, it has been reprinted everywhere, causing considerable controversy on the Korean Internet. Tiffany then deleted the photos, but the controversy has not subsided. South Korean netizens condemned her and asked her to take off the variety show. Subsequently, Tiffany uploaded a handwritten letter of apology.

Until the afternoon of 18, the program "Sister of Slumdog" reported through the media that "the program group and SM Entertainment Company discussed the problems caused by Tiffany uploading photos with the rising sun flag on sns in August of 15, and the result of the discussion was that Tiffany's behavior hurt people's hearts and caused bad influence, and finally decided to let Tiffany off the program".

In addition, Sister's Slum will not add new members in the short term, and will be launched in the form of five people. At present, the program "Ducks and Sisters in Slums" has been suspended due to the broadcast of Rio Olympic Games, which has nothing to do with the flag incident. The new program will be broadcast on the 26th.
