It is time for celebration for ONCEs all around the globe since TWICE released a new schedule for their sixth debut anniversary to be held on October 20. 

Following their timetable, they recently unveiled personal handwritten notes from the members of TWICE to their fans on their social media. They will release more "special letters and images" in the upcoming days.

A special group V Live is also scheduled to be broadcasted on October 20 KST. In addition, a special "surprise" gift is also mentioned from TWICE members to their fans on October 21.

TWICE was formed under the television program Sixteen and debuted on October 20, 2015. Since then, it set the record of being the first female Korean act in history to simultaneously top both Billboard's World Albums and World Digital Song Sales charts.

TWICE Recently Released Their First Full English Single and Are Hinting an Album Release

Kpop sensation TWICE started dropping teasers in August. Then, finally, they released their first-ever full English single titled 'The Feels' on October 1, right before they announced their anniversary celebrations for their fans.

While the girl group has released English versions of singles in the past, including 'More & More' and 'I Can't Stop Me,' the new single is an inspiration from the group's desire to communicate with ONCEs from the United States.

On the occasion of their album release and 6th debut anniversary, TWICE members talked to Bustle about their full English single.

"We wanted to communicate with them better," Nayeon added. "When we're doing a global tour, we try to sing our songs in their respective languages; when we're singing the song in their language, we just feel very proud."

TWICE also dropped a stunning group photo, announcing their third full album, Formula Of Love: O + T=<3, which will be released on November 12 at 2 pm KST. 

TWICE Members Went Candid to Share Their Dreams before Their Debut

Conversing with Bustle, the TWICE members reflected upon dreams before their debut and how the group has evolved since.  

Sana, originally from Japan, opened up about her dream pre-debut, of performing in front of her family in Japan. 

"I remember when we performed for an end of the year performance once in Japan," she said. "It was the first time that my family saw me live onstage and they loved it. It made me really happy to see them happy."

When asked how do her dreams from pre-debut compare to those from where she is right now, Momo revealed she had a mixture of both tiny and big dreams, but now that TWICE has become a global phenomenon in the music industry, it is almost shocking to her when she thinks about how much they have accomplished. 

Dahyun recollected her days in JYP of topping the rank of music charts when she was the first cast as a part of TWICE. Now that they receive kind words from fans worldwide, she noted that this synergy pushes her to show her best efforts on stage. 

Tzuyu also recollected her dream of holding concerts in Korea and overseas to meet people from all over the world. Her goals are getting even closer with the release of their first-ever full English single on October 1.
