Wheesung's agency has denied rumors of his involvement in former TV personality Amy's past propofol use.

Amy alleged on social media there was another celebrity involved in the past drug scandal that led to her deportation, and after Wheesung fell under suspicion, his agency has now returned with a statement. On April 17, Wheesung's label Real Slow Company stated, "We are clearly stating the suspicions regarding Wheesung that were mentioned on social media on the 16th are completely false. Wheesung has definitely not committed these actions, and if there is an audio recording as claimed, he will receive the punishment appropriately."

Real Slow Company continued, "Wheesung was already ruled not guilty on the charges of injecting propofol in 2013 during his military service. He underwent intensive investigation by the military police, and we're stating once again he was cleared of the charges as it was proven it was for medical treatment purposes by doctor's diagnosis. After his incident, he was investigated for using sleeping pills as well, and this indictment was also suspended."

The agency concluded it was painful for Wheesung to release the statement and apologized for raising trouble because of past incidents.
