Wheesung ultimately decided to cancel his concert.
On April 17, the organizer of Wheesung and K.Will's 'Bromance Show' announced the concert, which was originally scheduled for Seoul, Jeonju, Busan, and Daegu on May 4-5, has been canceled due to "an inevitable situation."
The event organizer apologized for the cancelation and promised to give a full refund to fans.
Meanwhile, Wheesung has been rumored to be the male celebrity who used drugs with Amy in the past. The singer's agency denied the rumors, however, he's continued to be suspected.
