Among 98 contestants in "Produce 101" season two, 26 trainees have already debuted in the past. Seven of them stand out the most because they have great talents and skills.

Among some contestants, NU'EST members stood out the most because they debuted five years ago. This boy group from Pledis Entertainment decided to join "Produce 101" because they thought that they weren't that successful and they wanted to use the show as their last chance. The four members who are currently competing to be in the top 11 are Kang Dongho, Choi Minki, Kim Jong Hyun, and Hwang Min Hyun

Next, according to AllKpop, another contestant that has debut experience is Samuel. He has debuted with rapper One using the name One Punch. Samuel previously used Punch as his stage name together with One. When One left, Samuel also experienced singing solo. He was really young back then.

It was unfortunate that discrimination was still there. Samuel was reported being bullied in school as there was a message from anonymous netizen telling that Samuel was bullied by his friends at his school. But according to the message, he stayed calm and kept showing his confidence, Koreaboo reported.

Next, there are two boys from Jackie Chan Group Korea's Kim Chan Yul and Choi Ha Don. They are known as JJCC's Yul and Sancheong. They debuted in 2014 with the single "At First."

The four members of NU'EST are the ones that bring many controversies because many netizens think that it is unfair for them to enter the show. They have got much experience compared to other trainees and it seems unfair for other contestants.

Recently, NU'EST's old album climbed up again on music charts. Many believe that it was because of their appearance on "Produce 101." Even though those seven trainees have debut experience, they need to show their best performance to be able to take the spot in top 11.
