## Background and release

South Korean singer-songwriter IU had been gaining popularity in 2010 with the release of her collaborative hit single "Nagging" with Lim Seul-ong and her starring role in the South Korean variety show Heroes. On December 2, 2010, IU announced that she would release her third extended play (EP), Real, on December 9. The album peaked at number two on the Circle Album Chart (previously known as Gaon Album Chart) in the issue dated December 26, 2010 – January 1, 2011, and it has been retrospectively identified as the start of IU's rise to stardom, also thanks to the success of its lead single "Good Day".
On December 2, it was also announced that MBLAQ's member Thunder would feature on Real's b-side track "Merry Christmas Ahead". Written by Shinsadong Tiger, Choi Kyu-sung and Choi Gap-won, "Merry Christmas Ahead" is a Christmas love song, written as a confession from IU to her fans. IU stated that the song originally didn't suit her taste, but she came to like it. She said it is a "special" project to her since it features Thunder and Shinsadong Tiger, who had been her friends since they were trainees. IU said: "Sang-hyun oppa (Thunder), Ho-yang oppa (Shinsadong Tiger) and I were together when the three of us were nothing, but the fact that the three of us got together and did something makes me proud".

The song debuted at number 24 on the weekly Circle Digital Chart (previously known as Gaon Digital Chart) in the issue dated December 12–18, 2010, and peaked at number 7 in the chart issue dated December 19–25, 2010.

## Legacy

"Merry Christmas Ahead" has become one of the most popular South Korean Christmas songs. Jung Byeong-geun of The Fact wrote that it has been "reigning as the strongest Korean carol ever" since it was released. The song has been nicknamed a "Christmas Zombie" since it manages to re-enter charts each year, despite the declining popularity of Christmas songs in South Korea. It has been compared to Busker Busker's "Cherry Blossom Ending" for its seasonal appeal and longevity on charts. Its acronym, Mimek (Korean: 미메크), has been used as an alternative way to wish a "Merry Christmas".
The song placed at number 18 on the list of the top 100 songs of the 2010s by streams and digital downloads released by the largest Korean music streaming service, Melon. It was the only Korean song to be featured on DJ Park Myung-soo's list of the top five carol songs, ranking third. Insight placed it on its list of IU's 14 most famous songs, released in occasion of her 10th debut anniversary. "Merry Christmas Ahead" has also been covered by multiple artists, including Laboum, Kim Se-jeong, Yoo Jae-seok, and Stray Kids.
