During a recent livestream, ICHILLIN’s Joonie offered fans a behind-the-scenes glimpse into her trainee days, revealing a meaningful and unusual assignment she and her fellow trainees once undertook: studying a BTS documentary.
According to Joonie, this wasn’t just casual viewing—it was part of their pre-debut training, designed to help them reflect on the deeper realities of life as a K-pop idol.
Although she didn’t recall exactly which BTS documentary they watched, Joonie explained that the documentary portrayed the BTS members’ struggles, resilience, and journey through their formative trainee years.

After watching it, trainees were required to write about their thoughts and lessons learned, focusing on the emotional and practical challenges faced by BTS during their rise to fame.
“We had to write like notes on how we felt about it, what we learned… The documentary was about what the BTS sunbaenims felt and went through during their trainee days and how they endured it,” Joonie said.
This assignment was reportedly meant to instill core values like humility, perseverance, and gratitude—qualities BTS is often praised for.
By reflecting on the sacrifices and hard work that BTS endured, trainees were encouraged to better understand the depth of commitment required in the K-pop industry.
The revelation highlights the significant influence BTS has had not just on fans, but on aspiring idols themselves.

Their story continues to serve as both a blueprint and a source of motivation for the next generation of artists navigating the difficult road to debut.
