The group's second album, released in 2000, was also successful and included the songs "Ready For Love", "Always in My Heart", and "Mosun" (모순; lit.
[5] In June 2016, Jung Ye-bin (now using her real name, Gong Seo-young), Chae Eun-jung, and Kim Ha-na appeared on Two Yoo Project Sugar Man, performing "Good Time".
However, the CEO of their agency decided to switch to a fairy concept after considering the trend of girl groups at the time.
Park Ye-eun had a lot of connections in the music industry and directly cast Chae Eun-jung on the street before adding Kim Ha-na to the group through an audition.
The title track of their first album was "Good Time", a catchy song that became very popular among female students in grades 1 to 9 who were born between 1982 and 1989, after Fin.K.L, S.E.S., and Baby Vox.
Despite its upbeat melody, the lyrics were quite explicit at the time, saying that they wanted to spend the night with someone but needed their parents' permission.
The second album era of Cleo is considered the best period in the group's history, and it is a memorable activity that secured popularity and recognition among the public in the 2010s.
In fact, the early 2000s were the peak of Cleo's heyday, and there is an overwhelming amount of material from the second album era on YouTube.
Chae Eun-jung, who was already the most popular member since the first album and ranked high in the popularity ranking of girl group members, transformed her innocent image from the first album to a mature image by dyeing her hair blonde for "Ready For Love."
Han Hyun-jung, the new member who joined to replace Park Ye-eun, had a strikingly pretty appearance, unique falsetto singing style, and decent dance skills.
"Ready For Love" is a fast-paced Euro dance song that helped make Cleo a popular girl group in the early 2000s.
This activity marked the beginning of Cleo's heyday, as they maintained steady popularity even during the comebacks of larger girl groups.
She managed to cover herself with one hand while continuing the dance, and even showed off a special performance at the end, receiving praise from fans for her professionalism.
However, there were concerns from the public about trying to transform from a lively image to a sexy one, as it overlapped with Baek Ji-young, who was also active in Latin dance music at the time.
"Ready for Love" is a highly popular song that formed a major part of Cleo's discography alongside "Contradiction."
The album version is closer to a dance song with inserted Latin music elements and a similar beat, but without Han Hyun-jung's chorus part.
Their second album firmly established Cleo's image and contributed greatly to their success, with appropriate sales and popularity that remained relevant even in the 2010s.
The title track of their third album, "Triple," was a techno dance song with high-pitched vocals and a fast beat.
During their third album promotion, MBC Music Camp was cancelled due to the YeonJeHup labor dispute and they were unable to perform live because the show switched to a pre-recorded format.
The lyrics and melody matched well with the feelings of many couples, making it a highly popular song among female students.
During that time, "Fairy Tale" was a popular song that girls sang at karaoke or added to their backgrounds on websites like Cyworld.
After the departure of Chae Eun-jung, the group recruited a new member named Jung Ye-bin (Gong Seo-young) and released their fifth studio album 'Rising Again' in 2004 with the title track 'In & Out.'
In 2016, Cleo members Kim Hana, Chae Eun-jung, and Gong Seo-yeong appeared as the Hee-yeol team on the show "Two Yoo Project Sugar Man."
While Chae Eun-jung went to Hong Kong and became a member of a group called Girls' Kingdom along with Japanese model Anna Kubo.
During the show, Kim Hana and Chae Eun-jung reminisced about how they fought a lot during their team activities because they were sensitive to each other, but they didn't have any big fights.
