On January 25th, 11 AM KST, YG Treasure Box revealed that the final member for the debuting group will be Choi Hyunsuk. Hyunsuk previously competed on another YG survival show,MIXNINE, and ended up taking 5th place for the debut lineup. In addition, Hyunsuk had the fourth highest VLIVE followers with 94,000+.

While his debut was anticipated by many international watchers and fans, k-netz expressed their disappointment with YG's choice to debut Hyunsuk. Many k-netz wanted Ha Yoonbin in the final lineup. After Hyunsuk was revealed to be the 7th and final member, k-netz and Korean"Binnies" (Ha Yoonbin's fandom), started to trend on Instagram and Twitter a hate hashtag,#YG보석함_논란멤버_번복해. The tag was created to kick out Hyunsuk in order to debut Ha Yoonbin. K-Binnies relayed the same hashtag to I-Binnies and stated that the hashtags were to "add more members." The k-netz began posting on YG coaches personal Instagrams and forced several of these coaches to turn their Instagram from Public to Private. 

However, majority of the k-netz state that Hyunsuk should not debut because he is "too old" and his visuals are "unappealing." Hyunsuk was born in April 1999 and is currently 19 years old. 

In the fabricated rumors, the fans claimed that Hyunsuk was a bully with no evidence of being in contact with the trainee. An anonymous ex-YG trainee stepped up days prior on DC Gall, and praised Hyunsuk for his kind and welcoming nature, wishing for the best and their sincere hopes for Hyunsuk to debut. Another ex-trainee, Jinny also praised Hyunsuk for his kind manners. And in several diary cams from different trainees (Keita, Yoshinori, Jihoon, Junhyuk etc.) on YG Treasure Box, praised Hyunsuk for his selfless nature in helping their practice over his own.

Hyunsuk is known to be one of the few trainees on YG Treasure Box, who is an all-rounder, having expertise as a producer, composer, lyricist, choreographer, dancer, rapper, and vocalist. Hyunsuk has choreographed several performances on Treasure Box as revealed on his Diary Cams.  

Below are some of his performance clips and examples of his choreography. 

[UPDATE] : As word began to spread about the false rumors and hate hashtags created by k-netz, SKIES (Hyunsuk's fandom name), or Hyunsuknators, created an opposition hashtag on Twitter and managed to trend it.
