Changes

— On November 4, 2015, the name of their fan club was revealed through Instagram “ONCE”. Adding a message, saying: “A lot of fans liked the word 'ONCE'. 'Once & Twice'. 'ONCE' and then 'TWICE'. It seems that both words go together like thread and needle. If you love us even once, we will return your love twice. It is difficult to make some kind of relationship between people and obtaining the love of others is the most difficult of all. We will work hard to get them to look at us once and fall in love with TWICE. Let's be together until the end. We love you!".<br />
