SBS's "Strong Heart" held a "King of Kings" special on the June 21st broadcast. During this recording, SS501's Kim Hyun Joong confessed an interesting story titled, "Kim Hyun Joong's incarceration incident" and got everyone's attention. Back in 2007, Kim Hyun Joong went to a nightclub with some acquaintances while on vacation in Jeju Island. He revealed, "I was even singing while playing, but when I get drunk, my downfall is that I get really sleepy. I had to use the restroom, so I left briefly to go to the restroom. However, I don't recall anything that happened after that." When he woke up from his sleep, Hyun Joong first checked his text messages. His cell phone was off and when he turned it on, he had over 100 missed calls. After this, he was about to go back to sleep, but he suddenly realized that he couldn't remember where he was. Because it was dark and he couldn't see anything in front of him, Hyun Joong thought he might have been kidnapped and told himself to stay calm. He turned on his cell phone again to try and use the light to see what was in front of him, but after a second, his cell phone turned off again. He put on his shoes and started to touch the items in front of him. Kim Hyun Joong revealed, "I went back and forth touching the things in the room, but I felt a lot of buttons. When I pressed the buttons, they felt familiar. I thought to myself, 'Ah, this is the room from last night." The buttons were from the karaoke machine. As it turned out, when Kim Hyun Joong came back from the restroom, he accidently went into the wrong karaoke room in the club and fell asleep. His friends thought that Kim Hyun Joong went back to his dorm early, so they left the nightclub.  After, Kim Hyun Joong tried to exit the club, but the doors were locked and the phone inside the nightclub only had extension features. Kim Hyun Joong started to worry a bit more, but he finally got the door to open and escaped. However, when he came outside, he realized that his hair was a mess and he had no money. He tried to make a toll-free call to his friends, but his friends didn't pick up the phone because they were all asleep. Kim Hyun Joong stated, "Because my dorm was 40km (around 25 miles) away, I just sat on the street. I was just a beggar" - causing much laughter in the studio. Those around him joked around and stated, "You're a flower-beggar," playing on his title as a "flower boy" from "Boys over Flowers". Source: Newsen
