Donghyun’s Pre-debut Story

After discovering that the Jo twins starred in over 300 Commercial Films as child actors, netizens have become increasingly interested in the Boyfriend members’ pasts. This time, they found out that the leader, Donghyun, had actually starred in a KBS reality program named “Conduct Zero” a while back, and were surprised to learn that he was a bit of a rebel back in the day. “Conduct Zero” was a popular show that took six rebellious high school boys and aimed to transform them into model students with dreams to look forward to through the help of actor and strict mentor, Choi Min-soo.

Beneath his pretty-boy looks, Donghyun was a student who was fairly unruly. But it seems that he cleaned up pretty well, as netizens commented on how Donghyun transformed from a whiny young kid to a strong new leader. For those familiar with the show, Park Tae-yang has gone on to acting, while Lee Hwan is now a DJ and a model under Big Hit Entertainment.

Joined KBS ‘The Unit’ As Contestant

Kpop Chart

Starship Entertainment revealed that four of the six Boyfriend members would be on ‘The Unit’. There had been reports that Boyfriend would be joining the KBS idol-rebooting show, and Starship Entertainment confirmed that Donghyun, Jeongmin, Kwangmin, and Minwoo will be on the show.

The first open audience recording of ‘The Unit’ was scheduled for September 29 and 30. The first episode of the show was be broadcast on October 28 and the show had 14 episodes.

Have Same Fate As NU’EST’s JR?

Overnight is an unforgettable day for fans of KBS’s ‘The Unit’ survival program. The last episode that was aired live announced the nine members who entered the debut line-up. Unfortunately, one of the contestants who was believed to be entering is the leader Boyfriend, Kim Dong-hyun, who ranked 12th, so that he couldn’t get into the debut line-up in the last episode, even though he always had a pretty convincing rating beforehand.

This made netizens remember last year’s Mnet “Produce 101 Season 2” survival program where NU’EST’s leader Kim Jong-hyun, also known as JR, was unable to enter the line-up debut. Netizens made a lot of comments and wrote posts like:

“The last episode of ‘The Unit’ really reminded me of ‘Produce 101’ …”

“No need to regret, Donghyun will be happy like Jonghyun later …”

“The words ‘Boyfriend need more leader’ reminds me of ‘NU’EST needing more leaders’ …”

“For prospective survival contestants in the future, never show your leadership skills or you won’t enter the line-up debut …”

“I am a NU’EST’s fans, at first we did feel guilty but felt guilty without doing anything then it would be in vain right? I just want to say that if you support it then you have to support it to the end. Boyfriend fans, excited! ”
