Background and release
"Koisuru Hikari" was released approximately nine and a half months after the group's previous single "I Wish". The single was issued in three editions: a limited edition Type 1 (CD+DVD/Blu-ray), a limited edition Type 2 (CD+DVD/Blu-ray), and a regular edition (CD only).
The title track serves as the theme song for the film Koi o Shiranai Bokutachi wa, starring group member Ryusei Onishi, which was released nationwide on August 23, 2024. The song is described as a refreshing rock-influenced love song that emphasizes themes of youth and the frustration of being unable to fully express one’s feelings. Onishi commented that the song is “a warm track that gently encourages listeners,” reflecting elements of the film’s narrative.
On June 27, 2024, the song was made available on TikTok, where the members posted videos featuring the "#コイスルダンス" ("Koisuru Dance"). The music video premiered on YouTube on July 22. The song was first performed live during a livestream from the Yokohama Arena concert of their tour Naniwa Danshi LIVE TOUR 2024 '+Alpha' on August 13.
The group gave the song its first television performance on TV Asahi's Music Station on August 30, where member Shunsuke Michieda highlighted the choreography, noting that the hand movements resemble scrolling on a smartphone and are easy to imitate.
