The album produced a string of hit singles: "Poison", "Invitation" (초대; Chodae) and "Finding Hidden Image" (숨은 그림 찾기; Sumeun geurim chatgi).

Uhm recruited songwriter Joo Young-hoon to work on the release, following the unexpected success of "Rose of Betrayal" from her previous studio album, After Love, which he wrote and compose.

"[7] The album's lead single, "Poison", is an electronic dance track influenced by techno and hip-hop,[8][9][unreliable source] with a music video that featured actor Cha Seung-won when he first worked as a fashion model.

[11] The concert was themed as to declare a "transformation" from "an innocent girl to a mature woman", with Uhm's intent to create a "dramatic" stage with a storyline—similar to productions by American singers Madonna and Michael Jackson.

[12][13] Kim Gap-sik of DongA commented that she resembled the Roman god Janus, in that Uhm showcased both a "seemingly subtle sexy look" and a barefaced "girl next door" persona over its duration.

[15] In contrast, an "alluring and mysterious" image was introduced for the album's second single, "Invitation", in which Uhm wore her hair long, and performed with a hand fan in black dresses.

[16] In a retrospective article, American music magazine Billboard placed "Invitation" at number 49 in its list of the "98 Greatest Songs of 1998", with writer Tamar Herman noting its "dreamy sensuality" that "[allures] in its breathy vocal delivery and sleek synths".

[17] In 2021, the online music service Melon and the newspaper Seoul Shinmun collaborated on a "100 K-pop Masterpieces" special feature, which listed "Invitation" at number 67 as a "foothold" for Uhm's "avant-garde energy and a major source of queer aesthetics tributes".

A short sample of "Poison" appears at the end of American rock band Rage Against the Machine's 1999 single "Sleep Now in the Fire", after it was picked up from a local Korean radio station broadcast by the amplifier of their guitarist, Tom Morello.
