Often, it is difficult for K-pop singers to voice their concerns to their bosses, due to the hierarchical and extremely formal structure of South Korean society.
Gen Neo says: "You can compare someone's age to ranks in the military. The older the person is, the more one's respect has to be shown to them, even if the age gap is only a year.
"Of course, we're respectful of our seniors in Singaporean Chinese culture too, but imagine this rule taken up 10 notches. It makes it difficult for people to voice their opinions or disagree with people older than them."
He and Hung have since moved on to pursue other paths.
Gen Neo is working as a Mandopop singer-songwriter in China, while Hung is seeking dance opportunities here.
SKarf's Wong is reportedly also trying to break into the Mandopop market in China and Taiwan.
Regardless of where they are, Hung points out that being in the media spotlight will never be easy.
She says: "Things could be extreme in the K-pop industry, but as long as you're in the entertainment business, there will be expectations and pressure.
"It's not something we can avoid, but it's about learning to deal with it and receiving help if necessary. For anyone chasing their dreams of becoming a star, that's an important thing to think about."
