Things have always been tough for trainees as Shinhwa's Minwoo revealed on the February 23 episode of SBS' 'Healing Camp'. He shared that�SM Entertainment�knows how to keep their precious trainees under control.

He explained that he and�Eric�especially got very restless because they were barely able to get out of their dorms while they were under SM. The two decided to go out with the members of S.E.S, who were trainees at the time. They went out to eat then to karaoke when a couple of strange men came in.

At this point, both Eric and Minwoo freaked out because the atmosphere was so strange, and they were the only men there. He worried they would end up fighting and causing an incident?

One older man said, "You guys are SM rookies, right?" and Minwoo couldn't help but be in awe at this point to which Dongwan cut in, "You liked it a bit, right?" with a smile. �

Minwoo said, "So we had gotten caught. We shouldn't have given anything away and been like, 'What do you mean?' Eric said that, but I said, 'How'd you know?' I still don't know who they are."�The men at that point just left so he and Eric returned to the dorm, which was strangely empty.

When they went to the practice room, all the members had their heads on the floor with their hands behind their back. The director then talked to them, trying to confirm this fact. Minwoo and Eric hid the fact they were with the S.E.S trainees, saying they were just younger girls they knew, so the director told them to pack up and leave because they had no right to practice.

He found out it was a shock therapy by SM and that he almost really had to leave because of this incident. Do you think that was too harsh?
