In the K-Pop world, there are many idols who spent a very short trainee period before debuting. However, there are also idols who had to stay being a trainee for many years, practicing at the company since they were very young. The longer trainee period, the higher the risk, because if you can’t manage to debut, then you’ll have to leave to start over, accepting a waste of time.

For female idols, being a trainee for a long time is even more risky, as their youth can never be returned. Even after debuting, nothing can guarantee that you will be famous. Recently, Korean netizens made a list of the most typical cases of idols being a longtime trainee – and not all of them have been able to reach big success.

Miyeon used to be a trainee under YG Entertainment. Starting at the age of 14, Miyeon spent 5 years training at this company. She used to belong to Team Pink Punk – the line-up that would become BLACKPINK, and was even expected to debut. In the end, however, Miyeon was unable to debut with BLACKPINK and left the company.

Xiyeon is one of Pledis Entertainment’s most famous trainees, known as the ‘Pledis Princess’ or ‘Princess Xiyeon’. She spent 8 years training at the company, since her 3rd grade, which means she dedicated half of her youth for Pledis. Before her debut, Xiyeon was also a child actress who regularly appeared in MVs of her seniors such as After School, Orange Caramel, NU’EST, etc.

In 2016, Xiyeon competed at the survival show ‘Produce 101’ but was unfortunately eliminated and only ranked at No. 25. After a year, Xiyeon debuted with PRISTIN as the main rapper of the group.
