Oh My Girl promoted the album with a series of televised live performances on South Korea's music shows.

Promotion for Oh My Girl's second EP, Closer, ended in November 2015, and the group began preparing for their next album soon afterwards.

[2][3] On March 17, 2016, WM Entertainment announced that Oh My Girl would be releasing their third EP (also called a mini album).

In the lyrics, the narrator is a girl who has a secret crush on a guy, but feels like she is "somewhere in between a dream and reality" because she is uncertain that her affection is returned.

[15] The lead single of the album reissue, "Windy Day", is a folk-pop song composed by Öberg and Swedish producer Maria Marcus.

[16] The lyrics, written by Seo and Mimi, express the complicated emotions of a girl's heart.

[17] The accompanying music video was filmed in Jeju Island in various outdoor settings, including a hedge maze and a forest.

[18] On March 28, Oh My Girl held a comeback showcase at the Lotte Card Center in the Mecenatpolis Mall, Hapjeong-dong, Seoul.

Doctors determined she had hyperventilated due to stress, and she took a few days off to rest, before resuming activities with the group on April 21.

[18] Pink Ocean entered the weekly Gaon Album Chart at number 5, selling 6,482 physical copies in three days.

[34] Billboard magazine's Tamar Herman called "Windy Day" experimental and quirky, and said it showcased the members youthful vocals.
