The EP contains three tracks, including the lead song "Masaka Naku to wa Omowanakatta", which was pre-released digitally on April 10, 2025, ahead of the CD release.

The title track was used as the theme song for the television drama Shissōnin Sōsakuhan Kieta Shinjitsu.

The release of the EP was announced on March 29, 2025.

"Masaka Naku to wa Omowanakatta" became the group's first title track with a Japanese-language title. The group described the title song as "a track deeply linked to the story of the drama".

Composition and themes

The fashion magazine An An described the EP as consisting of three contrasting songs: the ballad "Masaka Naku to wa Omowanakatta", the summer-themed track "Hot Summer", and the dance number "Attention".

Member YUHI described the title track as a "classic ballad" and stated that he performed it while overlapping the lyrics with his own personal experiences.

SHOW stated that the song expresses "the sadness of losing a loved one and the emotions of being unable to move forward" through the performances of the group's three vocalists.

SHOW also described "Hot Summer" as the group's first summer-themed song, adding that listeners should pay attention to the performers' participation parts that are not included in the lyric booklet.
