The single was released in two formats: the limited edition, which includes a bonus DVD featuring the music video for "Usotsuki," and standard CD-only edition.
"Usotsuki" is Ueto's first single without a tie-in since "Binetsu" (2003).[1] The title track was written and produced by singer-songwriter Tetsurō Oda, marking their fourth consecutive collaboration.[1] The song speaks about honesty in a relationship, and how a simple lie can change everything.[1] CDJournal described "Usotsuki" as a "bittersweet folk-pop song that pulls at the heartstrings of Japanese people."[2] "Usotsuki" marks Ueto's return to a darker image, reminiscent of her first two singles "Pureness" and "Kizuna".[1]
The single also includes a remixed version of "Ano Hito ni Aitai," the song used in Oronamin C commercial series, starring Ueto herself, and an acoustic version of "Kaze".[1]
