History

2002–2005: Boy'z
Boy'z was formerly a Hong Kong Cantopop duo that consisted of members Kenny Kwan (關智斌) (born 30 December 1980) and Steven Cheung (張致恆) (born 10 November 1984). The duo was formed around June 2002 by the Emperor Entertainment Group as the male version a year after the female Cantopop duo Twins was formed. Boy'z has released 3 EPs and two albums. Their debut EP, La La 世界 (La La World), was released in 2003.

They were based on another Hong Kong popular prefabricated duo, Twins, who was also formed by Emperor Entertainment Group. Boy'z received main roles in films such as The Death Curse (2003) and PaPa Loves You (2004). They were cameos as robbers in Jackie Chan's film New Police Story (2004). As their popularity grew, Boy'z gained their starring roles in the film, 6:00 AM (2004).

On 13 January 2005, it was announced that Boy'z would be splitting and disband as early plans and Kenny Kwan would continue his career as a solo artist. In February 2005, Dennis Mak (麥子豪, born 7 May 1987), top 5 finalist of the EEG Singing Contest 2004, who was originally planned to have a solo career, will continue Boy'z with Steven Cheung. The duo's popularity went down after Kenny left, mainly because they have not released any recorded material since then. Dennis and Steven were arranged to train in dancing and gymnastics. Then, they were spotted by a management company in Japan and wanted to sign them but their manager did not release them.

2006–2009: Sun Boy'z
On 26 June 2006, winner of 2003 International Chinese New Talent Singing Championship – Hong Kong Regional Finals, William Chan (陳偉霆, born 21 November 1985) joined the group and Boy'z was eventually renamed as Sun Boy'z. They released their first single called "Tic Tac Toe" shortly before June 2006, from their self-titled debut EP. This EP included the song "拜金小姐" which was sung and performed by only Dennis and Steven because the song was recorded prior to William joining the group. Therefore, the Mandarin version of this song, "好時代", had William on lead vocals completely. The group made a sudden street performance on 3 September 2006.

In early 2007, Sun Boy'z recorded the cover version of the song "Little Wonders" by Rob Thomas called "由夢開始" for the Hong Kong version of "Meet The Robinsons". On 2 January 2007, the group released a new music video and song "3+1=1". The song features former member Kenny Kwan and the title's meaning is referring to the four of them always being together as one, even though Kenny is no longer a member of the group. This song is on their greatest hits album All For 1, released on 22 March 2007. The album includes the best of Boy'z and Sun Boy'z songs along with 3 new songs. After having success in the cantopop music scene, their record company EEG decided to have them turn to mandopop and a new Mandarin album titled 初次約會 (First Date) was released on 17 December 2007. They have been promoting the new album in the Guangzhou and other parts of China since the release of the new album.

Their duet song "大不了 (No Big Deal)" along with a music video they recorded alongside labelmate Yumiko Cheng, was released on 1 February 2008 in Yumiko's album titled 超模 (Super Model). As Boy'z with Steven and Dennis, they had recorded about 3 unreleased songs, one of the songs is "拜金小姐" which they had performed live on several occasions. And as Sun Boy'z, they have released one self-titled EP and two albums up to date since 2006 with the newest album being a Mandarin album focusing on their Mandarin speaking fans.

They had done 3 advertisements, had a cameo in the film McDull, The Alumni (2006) and main roles in The Haunted School (2007). On 14 August 2006, a 45-minute-long music video titled Say Goodbye...Luisa from Isabella Leong's album Say Goodbye...Luisa (雪 再見) was released starring Isabella Leong and Steven Cheung while William Chan only had a guest appearance.

In April 2008, there have been rumours spread that William Chan would be separated from Sun Boy'z and go solo. It has been confirmed that William will begin to pursue a solo career and only appear publicly with Sun Boy'z once in a while. After William Chan left the group, Sun Boy'z became a cantopop duo with only Steven Cheung and Dennis Mak. It was officially confirmed in December 2008 that Sun Boy'z will disband with Dennis Mak leaving the entertainment industry. The reason to this decision is because he has decided to study Hotel Management in Switzerland. In the meantime, Steven Cheung, William Chan and Kenny Kwan would continue to pursue their careers as solo artists.

2010–present: Boy'z reunion
In 2010, Boy'z (Kenny Kwan and Steven Cheung) appeared on stage together in EEG 10th Anniversary Concert. In 2011, they released a new single together titled "Ready to Go".
