A music video directed by
Shin Hee-won was released on the same day as the single's release, featuring choreography by Ryu So-hee and Japanese dancer and choreographer
Rino Nakasone who has choreographed for other
S.M. Entertainment artists such as
TVXQ,
Girls' Generation and
Shinee. The members claimed that it was their most difficult choreography at the time. The music video begins with all five Red Velvet members at a play as 'rookie' performers. After being offered some mysterious pink smoke by member
Joy, a series of random and entertaining scenarios ensue where the members follow a floral-clad mascot in a 'Wonderland' while wearing various colorful outfits, such as blue and white
Alice-like dresses and continue the chase as they fly around in
spaceships. It ends with the members exiting the stage they first appeared in.
Billboard likened the girls in the video to
Alice in Wonderland's titular character, as they travel in a world that's part
Candyland and part
Yellow Submarine. The group performed the single on all of
South Korea's music programs (
Music Bank,
Inkigayo,
The Show,
Show Champion,
M! Countdown,
Show! Music Core) in February 2017, performing the song live for the first time on
Music Bank on February 3, 2017. To help promote the song overseas, Red Velvet headlined the
K-Pop Night Out concert during the 2017 SXSW Conference and Festivals at The Belmont on March 17, 2017, in
Austin, Texas which had over 2,500 spectators. A day later, they participated in
KCON Mexico. On April 16, the group had a fan event for the album in
Taipei. They flew to
Malaysia the next month to hold a two-day fanmeet at the LG Concourse of
Berjaya Times Square in
Kuala Lumpur, where they performed and promoted the song through a mini showcase for the EP. ==Critical reception==
