Hyesung revealed that he was scolded by SM Entertainment founder Lee Soo Man in the past.

All 6 Shinhwa members were guests on the May 16 episode of 'Happy Together 3'. On the program, MC Park Mi Sun asked them, "Since there are 6 of you, individually, you must have wanted to stand out on stage. Did you have something that you did to stand out?". Hyesung laughed as he�answered, "You know how you want to stand out more during your part? I wanted to look cool, so I danced too intensely for my part, even though it didn't really fit."

He demonstrated a bit while sitting down, and of course all the members knew exactly what he was talking about because Dongwan started to crack up next to him, saying, "It was exactly that." Hyesung revealed, "The members made fun of me, and Lee Soo Man was our CEO back then, and he scolded me, too."

Junjin stood up to demonstrate himself. It was actually a part from the debut song "The Solver", and Hyesung�over-exaggerated�the choreography and ended up looking a little ridiculous. He said, "We watched the performance while we were in the back and thought, 'What the heck is he doing?'".

Dongwan further revealed, "We all knew that he was just trying to work hard, so we made fun of him a little but didn't say much else. But what's funny is that after the stage, our manager told us, 'Lee Soo Man called me and told me to tell Hyesung not to do that.'" Junjin and Andy added, "He's not someone who would say something like that usually."

The story didn't end there as Eric had his own part to put in, saying, "After that, Lee Soo Man called us over to the recording studio, stood us all in a line, and said in a serious manner, 'Hyesung, don't do that again.'"

As a result, Hyesung revealed that he asked the choreographer to tell him what to do during his solo parts instead of his over-exaggerating ad-libs. The talk ended with Hyesung himself getting up and demonstrating what happened in 1997, cracking up everyone in the studio.
