The single had two tie-ups: "Makenai Kokoro" was used as the theme song of the television drama Gakeppuchi no Eri: Kono Yo de Ichiban Daichi na 'Kane' no Hanashi, while "Day By Day" was used in commercials for Avex Artist Academy.^[2] Band member Takahiro Nishijima featured as an actor in the seventh episode of Gakeppuchi no Eri.^{[citation needed]}

Six versions of the single exist: a CD only version, two DVD editions, and three Mu-Mo store exclusive versions.^[1] DVD edition A featured the music video for the song, while DVD edition B featured a documentary on the making of the music video for their previous single "Aitai Riyū."^[1]

All versions feature "Makenai Kokoro" and "Day By Day", while only the CD only version features the group's cover of H Jungle with T's 1995 number 1 single, "Wow War Tonight (Toki ni wa Okose yo Movement)".
