[4][5] On September 20, 2017, JYP Entertainment announced Got7's new extended play 7 for 7, revealing the title and the release date with a short video showing seven triangular pendants brought together to form the heptagon of the group's logo.

[1] Breaking away from the Flight Log trilogy, which represented the intensity of youth, the new record explores the coexistence of darkness and anxiety in it,[12] with instability as a central theme,[13] and focuses on showing the unity of the group as one.

[15] Leader JB, under the pseudonym Defsoul, worked on the alternative R&B piece "Teenager", and the pop and tropical house song "You Are", which he wrote and composed while promoting JJ Project's album Verse 2 in August.

[15][24] Yugyeom worked on "To Me", which expresses loneliness and fatigue;[20] the album ends with the electropop ballad "Face", a melancholy song about missing someone, which sees Jackson, Mark and BamBam writing the rap,[16][24] reflecting on their experience as foreign singers in Korea.

[13] For Hong You-kyoung of Korea JoongAng Daily, "Got7 challenges the notion that autumn is a solemn season with an upbeat sound on their cheerful and refreshing album 7 for 7, featuring energetic songs and a fun-loving vibe.

Instead, it focuses on the uplifting, mellow tones of the group's vocalists and counters them with hard-hitting raps from Got7's rappers, crafting an evocative pop-EDM track", "sentimental in its soaring builds and sweeping melodies".
