The images of singer Jung Eun-ji and Seo In-guk as a 'couple' have been revealed.

The agency raised fans' expectations by releasing individual concept photos of Jung Eun-ji and Seo In-guk's special single 'Couple' through official social media channels on the 12th and 13th at noon.

In the concept photos taken against the backdrop of an outdoor building and a recording studio, Seo In-guk drew a half heart on his cheek and checked a polaroid photo, smiling and elevating anticipation with a visual full of excitement.

Jung Eun-ji also showcased a similar look at the same location, looking up at the sky with a bright smile while playfully holding a polaroid camera, creating a natural and comfortable mood that hinted at the atmosphere of the new song 'Couple' the two will present together.

Set to be released on the 16th, Jung Eun-ji and Seo In-guk's 'Couple' is a duet that reinterprets Sechs Kies' 'Couple,' released in 1998, with refreshing spring vibes and band sounds. Arranging it were Aaron Kim and Isaac Han, who have worked with Red Velvet and Tomorrow X Together, adding a fresher band sound to the familiar lead melody intro of the original song, thereby completing the harmony with the two artists' voices.

Jung Eun-ji and Seo In-guk collaborated as the main characters Yoon Yoon-jae and Sung Si-won in the 2012 tvN drama 'Reply 1997,' and the OST they personally sang, 'All For You,' induced viewers' immersion with its sweet love song, leaving a lasting impression. In this new song, the two will actively participate in the entire production process, sharing many opinions to perfectly recreate the 'couple chemistry' from 13 years ago, conveying their heartfelt feelings to fans who have been waiting for their reunion.

Jung Eun-ji and Seo In-guk's duet song 'Couple' will be released on March 16 at 6 p.m. through various online music sites.
