He debuted in 2003 when he was 18 as the lead vocal in the boyband K ONE. The band was known as the "best dancers of Taiwan". They released their first album "We r K ONE". In 2004, all the members acted in the drama Top on Forbidden City along with Joanne Zeng and members of 5566. The OST for this drama had the most singers than any other drama (at that time, i'm pretty sure). In 2005, they released their second album "Love Power". This was the height of their popularity and were first in pre-order sales. Around this time, JR began his hosting career with shows such as Wan Quan Yu Le. In 2006, they released their third, and my favorite, album "Romeo and Juliet: Love Story". In 2007, they released the single "Kingly Way" and last album "Beautiful Commemoration". In 2008, they began promotions in Mainland China. Sometime after, they disbanded.
