Minhyun talks about how upset he was at NU'EST's lack of popularity

The 'Happy Together 3' episode with the members of Wanna One continued on August 10. 

The oldest member Yoon Ji Sung revealed, "I was a trainee for about 7 years and I lived at a goshiwon (a very small room students live in to focus in studying). I had a hard time because of fruit flies. I saw fruit flies laying eggs and even mating." 

He continued to shock as he revealed that there was no heating at the goshiwon. Yoon Ji Sung said, "But the hot water worked so I turned the water on and slept near there."

Minhyun also shared his past hardships, and said, "I debuted as a member of NU'EST in 2012. At the time, I thought we would immediately become super stars if we debut. But I had a really hard time.."

He explained, "There were 100 seats available for our fan sign event but only 50-70 people came. I was really upset."
