The album was released in South Korea on February 25, 2015 with "Black Swan" as the lead single.
In the clip, each member is outfitted in a unique all white dress shedding their girl-next-door image for a more mature tone.
The agency said: “With last week’s music show, [Rainbow’s] ‘Black Swan’ promotions have come to an end.
Many thanks to all the fans who supported Rainbow’s third mini album, and we’ll work hard to return new and improved.
Thank you.”'[3] The songs were unable to give them a spot in the top 100 and failed to garner significant interest, resulting in the early termination of promotions.
