Blueming (stylized BLUEMING) is the sixth extended play by South Korean band CNBLUE. It was released on April 4, 2016, under FNC Entertainment and distributed by LOEN Entertainment. The band began developing the record within the same time period as "Cinderella" from 2gether (2015). Writing and recording for the album commenced in midst of the 2015 CNBLUE Live "Come Together" concert tour. Upon its completion, the band's record label announced that the quartet would release a mini-album.

Musically, Blueming is a pop rock record filled with songs which suit the spring season. Following a series of photo and video teasers, the mini-album and lead single "You're So Fine" were concurrently released. Blueming topped the weekly Gaon Album Chart and received favorable reviews from music critics. CNBLUE began promoting the record on music chart programs across various television networks by performing the single.

Upon their debut with Bluetory (2010), CNBLUE was met with immediate commercial success. Within two weeks, the quartet earned their first music show win with "I'm a Loner". With the albums that followed, the band did not meet the same instant success. With the addition of crafting their own music, CNBLUE faced mounting pressure which "daunted the band members for years".

On March 16, 2016, it was reported that CNBLUE was scheduled to release an album in early April. Six days later, it was announced that the band would release a mini-album entitled Blueming on April 4. A portmanteau of "CNBLUE" and "blooming", the record is meant to showcase the "blossoming of CNBLUE's new musical horizons". The release of the mini-album comes off the heels of the 2015 CNBLUE Live "Come Together" concert tour.

CNBLUE began conceiving Blueming while developing "Cinderella". Between the members' solo activities and CNBLUE's concert tours, the bandmates took the opportunity to record songs. Although not intended coincide with the spring season, vocalist Jung Yong-hwa sought to release "refreshing, breezy music" as soon as possible. Unlike with previous releases, the band did not pen any specific song with the intention of releasing it as a lead single. Instead, CNBLUE chose from a pool of songs which they had written. The band deliberated between "You're So Fine" and "Young Forever"; they agreed upon the former because it "sounded the best".
