Definition Kpop Idol. It is derived from the original way the word is used to have a bias towards someone. Kpop is Korean pop.
The aim of the show was to decide the best new young pop singer in the UK based on viewer voting and participation. K-pop or the songs performed by these idols are both incredibly gifted and malleable. You may see these idols always smiling with pleasing personalities but not everyone is genuine to themselves.
We all love eccentric wacky and sah extra idols.
By releasing the song they are making their first public appearance and performance as an Idol instead of a trainee. SHINees Onew APinks Chorong etc Sometimes the leader can be the member who was a trainee for the longest period of time out of all the members of the band. Idols sell their reputation. The girl groups can serve too but there is currently no information about them having to.
