It spawned four hit singles and earned Uhm Golden Disk Awards.

Uhm worked with various South Korean producers and songwriters on the album, including Kim Chang-hwan [ko], Joo Young-hoon, and Jung Jae-hyung among others.

Yang Seong-hui of Munhwa Ilbo said, "Uhm now has an indisputable position in the dance music industry following the success of her songs, 'Poison', 'Invitation', and 'I Don't Know'."

However, Park Eun-joo of Hankook Ilbo cited an anonymous source, criticising her for using "too much sex-appeal" but Park also said that Uhm's performances were positively received by the public.
