K One

K One was a Taiwanese boy band. The five-member band was formed in 2003 and disbanded in 2008.

History
K One belongs to the management company, Wingman, managed by former 5566 member, Rio Peng. Other artists that belong to this company include 劉耕宏Will Liu, Evonne Hsu許慧欣 (eVonne), Ivy (許嘉凌, eVonne's sister), Alicia(潘瑋儀), Vivi (夏如芝), Niki, 無限(Freddy and Teddy), Wing, Style (浩偉and宏霖), and育緯.

The band was founded in 2002. It collaborated with five agents and five record companies during its existence. The band members are Tsai Shang Fu ("Gino"), Chiang Chun Jui , Chien Hsiao Ju , Hsiao Li Yang , and Cheng Jen Hao.

Gino was the group's leader. For the TV series Top on The Forbidden City in which K One members starred, the band in 2004 published a soundtrack album bearing the same name. The album had strong sales. The group topped G-Music's Mandarin Chart in July 2005 and topped two other charts. According to Apple Daily, "this proves that although the idol product revision strategy has always been criticized by fans, there are still many people who buy it". Eastday in 2005 called K One "Taiwan's most electronic dance music group". The band released their second album Love Power on 13 May 2005.

The group released their third album, Love Story of Romeo & Juliet, in 2006. Owing to problems like the songs initially being criticised and business issues, the album's planned release date of February 2006 was revised to October of that year. They filmed the music videos for the songs "If there was no tomorrow" and "Look into my eyes" at Linkou District. The songs infuse elements of dance music, classical music, and hip hop. In 2008, Sina Entertainment said that K One "has a high popularity in Taiwan" and did not visit the mainland much though they visited a Chongqing Broadcasting Group show called Entertainment Star Factory that year.

With five people splitting the profits, it was difficult to operate especially with the members doing side jobs. K One disbanded in 2008. In interviews in 2015 and 2016, Gino said the group members were incompatible and said JR insisted on keeping his career in Taiwan and did not want to join the group in performing in mainland China.

Timeline
This 5-man dance group, K One, was formed by Rio Peng, with his company Corvette Entertainment (the name Corvette was later abandoned in 2006 in favour of Wingman Entertainment). However, K One did not do well with their first album; a very likely reason is that Peng did not wish to involve his own artistes with 5566, hoping that K One would make a name for themselves. Another possible reason is that there was already another popular dance group, Energy, in existence; due to this, few people were excited about the arrival of K One. However, Peng ultimately did place K One with Jungiery the following year.
 * 2003

After K One was placed under Jungiery, they were soon put to act in the idol drama, Top on the Forbidden City 紫禁之巔. This idol drama had a lead cast roster of Gino and JR, and Joanne from the girl group Sweety. To help up this drama's fame, Sam Wang from 5566 also played a supporting role in the drama, and the theme song for this drama, Twist The Fate 风云变色, was a collaborated work by both 5566 and K-One. This strategy was once again successful; K One's fame rose sharply.
