Billlie continues telling the story of 'the Billage of perception: Chapter 3.'

On March 21 at midnight KST, the girls unveiled a prequel film preparing for their comeback with their 4th mini-album. In this latest teaser, the narration shares the story of an "enchanting night~ white night" and begins by saying, "I spend the most time reading books. Reading books and throwing them away is what I repeat every day. What remain are some books and the clarinet and ring you left behind," and brings you into a dream world.

Check out the 'prelude film' revealed on this day and stay tuned until the album release on March 28 at 6 PM KST.
