Before actually starting to receive the chance to release his first album he went through a lot of hard work.

He first entered Alpha Music in 1999, where he worked as a host under Jacky Wu's branch of artists before quitting in 2002.

Ko was eventually mentored as he befriended Jay Chou, who told him that he should know how to write his own songs, so that people would want to listen to his music.

Within six years of preparation, Ko eventually selected the best 12 songs for all the people anticipating for his music.

On August 19, 2005, Alan Kuo's first album came out with 12 songs and gained heavy support by famous Hong Kong singer/actor, Jacky Cheung.
