A cheerful Christmas song, the single for Show Me Your Love was released on December 15th, 2005, and featured the title track along with two others, one by each individual group. In a big marketing move by SM Entertainment, Super Junior 05 collaborated with the already-popular boy band Dong Bang Shin Ki for the song Show Me Your Love. To date, approximately 94,000 copies of SuperJunior05 have been sold.

On March 21st, Miracle was released in Thailand and reached number one on their charts as well. Miracle was released as a single on February 12th, 2006, and reached the top spot on the Airplay ranking for three straight weeks. This included the album's first track Miracle, the second single from the album. The album SuperJunior05 featured all of the songs from the digital single along with five other songs. TWINS (Knock Out), a cover of the 2003 song Knock Out by British boy band Triple Eight, is one of five tracks featured on the single, which demonstrated a wide variety of musical styles including rock-influenced R&B and soft bubblegum pop. On the 8th, this song was released as a digital single. The day after the album's release, Super Junior 05 debuted officially as a group, performing the song TWINS (Knock Out) on SBS Inkigayo. This album sold 28,536 copies in the first month of its release, reaching number one on the weekly ranking Hanteo and third place on the monthly ranking MIAK K-pop. Super Junior 05 released their eponymous first album: SuperJunior05 on November 5th, 2005. However, these performances were not part of their official debut and were not aired until May 16th, 2006, as part of the 25-episode documentary Super Junior Show. The band's first performance was on September 11th, 2005, for the television channel M.net, and featured members dancing to hip-hop songs including Take it to The Floor by B2K and Usher's Caught Up. On May 23rd, 2006, the band's thirteenth member, Kyuhyun, was added, and the band's name changed simply to Super Junior. However, SM Entertainment gave up on that idea the following year, much to the excitement of fans who had grown to love the members. The next year, the members would have been changed, making a new generation called Super Junior 06. The name Super Junior 05 was meant to indicate the year of 2005, and thus, the band's line-up for that year. Initially, the group was titled Super Junior 05, planned as a rotation band like the Japanese group Morning Musume., where the older members would be changed out every year, always altering the band's line-up. It is said that, in a picnic with many of the SM Entertainment trainees, the producers, seeing the talent that each of the members of the future band had, said that they were "super", hence forming the band's present name, Super Junior. Shortly thereafter, the band's name changed to Junior, due to the members' young ages at the time. The band's name was originally O.V.E.R., an acronym for "Obey the Voice for Each Rhythm", and they were being promoted as the "gateway to stardom in Asia". Thus, they became the first 12 members of the world's largest boy band. The band's initial line-up included Leeteuk, Heechul, Han Geng, Yesung, Kangin, Shindong, Sungmin, Eunhyuk, Donghae, Siwon, Ryeowook and Kibum. The members were carefully selected, the majority having already had previous experience in the entertainment world. The rumors became real when the creation of a 12-member boy band was announced in the beginning of 2005.

In the 2000s, with the rising success of BoA, and the 2003-created band Dong Bang Shin Ki, there were rumors that Lee Soo Man would be creating a new boy band. Both of these bands reached a high level of success in Korea, resulting in the creation of other bands like Shinhwa and Fly to the Sky. Based on the results of this research, the bands H.O.T. SM Entertainment was created on February 14th, 1995, by South Korean Lee Soo Man, who researched to find out what the teenagers of the time would like to see in a group. The band was created by SM Entertainment, one of the most successful companies in Korea's entertainment industry. On November 6th, 2005, Super Junior, one of the largest boy bands in the world, composed of 12 members, made its debut on SBS Inkigayo.
