Yet, a recent announcement regarding TXT‘s Yeonjun has sparked fury.

Earlier in the year, Yeonjun and KATSEYE’s Daniela sparked shock with their chemistry in the track “Let Me Tell You.”

While netizens normally love collaborations, this sparked fury due to the “suggestive” nature of the choreography between Yeonjun and Daniela. They added that it was disgusting that, as soon as Yoonchae turned 18, they thought this was appropriate, especially due to the age gap with Yeonjun and the fact that she is still counted as a minor in Korea.
Disgusting to make a girl that JUST turned 18 sing a suggestive song w suggestive choreography with a man much older than her https://t.co/U6Ui4vmxyu
