Delight

On October 16, they officially introduced new member SooA, who had been performing with the group since July, through comeback teasers and also marking a release with the new lineup for the 24th. On October 24, Delight released their second mini album, School Bell's Ringing. After a brief hiatus, Delight resumed promotions in June 2014 with another lineup change.

Member SooA was absent and was replaced by a new, unidentified member. In early July, the group’s social media accounts were updated to show a five-member lineup, though two members were not yet publicly identified. And later, on July 21, a comeback teaser was released, officially introducing the updated lineup: Eunsae, Yeondu, Taehee, and new members Sumin and Jaewon.

The next day, July 22, they made their comeback with their third digital single, "Hate You! ". On February 6, 2015, teasers featuring Yeondu were released.

A few days later, on the 12th, Bros Media Entertainment revealed that she would be making her solo debut, while member Jaewon had been admitted to Dongduk Women’s University. Eventually, Yeondu officially debuted as a soloist on February 23, 2015, with the mini album Be Your Girl. After her solo promotions, the group and company fell silent, with their social media gradually disappearing.

Delight presumably disbanded in 2015 following inactivity, Facebook deletion, and Twitter rebranding. Following the disbandment of Delight, all the members went their separate ways: - SooA went on to re-debut in May Queen in 2014, FLASHE in 2017, Walwari in 2019, then MINIMANI in 2020, under the name Soohyun. - She later made her solo debut on March 1, 2023 with the digital single "Chuk & Chak".

- The circumstances of the other members are still currently unknown.
