"Miss Korea" A music video teaser for "Miss Korea" (), a pre-release single from the album, was unveiled on May 2, 2013. The video directed by South Korean
music video director Cha Eun-taek, and the single itself was released four days later. The self-composed song contains the message of comfort and hope, comparing all women to
Miss Korea, as the end of the song follows, "Are others' eyes that important? / Does it feel like it's your fault when something goes bad? / No, it's not like that, come here / It'll be okay, you're a Miss Korea". The lyrics was later donated to the
Hangang Bridge, as part of "the Bridge of Life" project promoted by
Samsung Life Insurance. Upon its release, "Miss Korea" debuted at number one on both the
Gaon Singles and Download Charts. It peaked at number three on the
Billboard Korea K-Pop Hot 100 for the week of May 25, 2013. As of , "Miss Korea" has sold about a million digital copies in South Korea. Lee personally selected 30 non-celebrity women "with love and respect for themselves" who she saw as the genuine "Miss Korea"s, to perform the song together on stage at the 2013
SBS Gayo Daejeon televised concert.
Jessica Jung, former member of girl group
Girls' Generation, covered this song at the concert ''SM Town Week Girls' Generation – Märchen Fantasy''.
"Bad Girls" The album's
lead single "Bad Girls" is a dance tune only consisted of acoustic band sound. Lee's self-written lyrics depicts the reality, in which confident women are considered "bad".
CJ E&M Music, the distributor of the album, released a video teaser for the track on May 15, 2013. As a parody of
SBS's current affair program
The Its Know, the teaser stimulates curiosity through narrations such as "Why did Lee Hyori become a bad girl?" and "From now on, we're going to unleash the truth about her". Lee spoofs
Sharon Stone's interrogation scene from the 1992 film
Basic Instinct. According to the singer's agency, two versions of the music video, a story-centered one and a choreography-centered one, would be released. The former features
cameo appearances from designer Yoni P,
Gil of
Leessang, model
Jang Yoon-ju,
Spica member Ju-hyun, and actress
Kim Seul-gi. The latter was released on May 23, 2013. "Bad Girls" went straight to number one on both the Gaon Singles and Download Charts in the first week of June 2013, as the album's pre-release single did. It also topped the
Billboard Korea K-Pop Hot 100 for the week of June 8, 2013, becoming her first song to reach the chart's pole position, a week after debuting at number 25. This song won the first place on televised
K-pop music shows like SBS's
The Music Trend,
KBS's
Music Bank,
MBC Music's
Show Champion, and
Mnet's
M! Countdown, from June 2 to 13. As of , "Bad Girls" has sold about 900,000 digital copies in South Korea. Lee performed "Bad Girls" as part of a highly praised collaboration stage at the 2013 SBS Gayo Daejeon televised concert, along with
CL from girl group

The Baddest Female". ==Promotion==
