With 'crazy' training to fit the rigorous standards, the process of becoming a K-pop idol is also likened to a real 'battle for survival'. But it is even more fierce for a group from zero to become a national treasure of kσrєα like BTS.

In a recent interview with a former employee who has been with BTS for many years, he revealed a terrifying truth about his training and working to become the group's top idols. Through the sharing of industry insiders, anyone must be surprised and wonder how the group can go through such exhausting days until now.

Here are the shares that I am sure any fan wants to hear to love the 7 boys more:

In kσrєα, being an idol is considered a career many people dream of. As an industry worth billions of dollars, idol groups in this country have now become an integral part of the pop culture of the 21st century. And one of the main representative names is BTS.

Unlike the training and debut model of artists from other countries, the system of training K-pop artists is formed by a much more specialized chain. Before becoming a real idol, they have to go through days of hard training and after that, there is also a "battle full of ̾b̾l̾o̾o̾d ̾, sweat and tears" to succeed on the path to becoming idols.

Of course, BTS is also living proof of that. To reach the heights like at the moment, BTS's success is not easy overnight as many people think, but in fact it is their tens of thousands of "sleepless" nights.

One of BTS' former employees who was present from their rookie days until the group's debut sheds light on how much they sacrificed to achieve their current success. Specifically, in an interview with Yonhap News, former BTS makeup artist Han Hyun Jae was asked about his most memorable moment while working for the group.

After that, he remembered their dedication to their career and could only say in a short sentence, “They practiced a lot.” This is not just the average practice frequency of an idol but much more than that.

Despite preparing for the schedule and completing a busy day, BTS will still sacrifice the little free time afterwards to practice. Han Hyun Jae shared, “They practiced after work with little sleep.”

And even when they did sleep, it was much less than half of the suggested hours an adult or growing teenager needs. Han Hyun Jae continued, “So they literally slept one or two hours, and then they came to the shop.”

Because of this, when the members went to the makeup room for the next schedule, they were too tired. Therefore, Han Hyun Jae spent most of his time working on their sleeping faces. He admitted, “For the most part, the time they were getting their makeup done was when they got some sleep.”

Han Hyun Jae remembered those times fondly, touched by how determined the members were to succeed. They went from rookies who barely slept and didn’t have time any free time to successful idols who can now do whatever they please.

After the sharing of the former BTS makeup artist, fans couldn't help but be touched by the efforts of all 7 boys:
