In May 2018, SM Entertainment announced Shinee would return with a new album to celebrate the group's tenth anniversary, including a fan meeting on May 27, 2018.

[5][4][6] Member Key noted that the reason why they wanted to release three lead singles is to show that the group is still here, working hard and doing well in coping with things as they are, referring to the grief they suffered from Jonghyun's death.

Additionally, "Our Page" is titled "The Words You Left Behind" in Korean and according to SM Entertainment, reflects the group's message of "We will be together until the end".

[17][16] The album artwork utilizes the five traditional Korean colors, or obangsaek: yellow, red, blue, white and black.

Key explained that they wanted to show "basic-but-Shinee style", as opposed to the "very complicated, different colors" that had previously featured in the group's imagery.

[18] The artwork was designed by SM's creative director Min Hee-jin, who used the three primary colors and basic shapes to convey "continuity and permanence".

[14] It was choreographed by Japanese dancer Koharu Sugawara, who had previously worked on Taemin's solo tracks like "Sayonara Hitori" (2016) and "Move" (2017).

[20] Like "Good Evening", the music video for "I Want You" features a CGI fox and also showcases old school green screen graphics recalling '80s sci-fi tropes.

[10][14] The accompanying music video to "Our Page" shows the four members working on their own and doing various activities before they eventually come together to perform the song atop of stairs with a fifth mic standing and left untouched.

[16] The music video for "Countless" depicts the members interacting with a variety of retro objects in a vibrantly colored, aqua-accented space, before assembling for the chorus.
