about kyuhyun :
Cho Kyu-Hyun (born February 3, 1988), best known mononymously as Kyuhyun, is a Korean pop singer. He is the last member to join the boy band Super Junior. He is the “maknae” (youngest) of the Super Junior members. He is considered as one of the four lead vocalists of the group. He is also one of the first four Korean artists to appear on Chinese postage stamps. He is nicknamed “GameKyu” because he likes to play computer games and is very good at it.
Kyuhyun made his first appearance as a part of Super Junior in a news broadcast on May 23, 2006 when the group was introducing their new single, U. Kyuhyun made his debut performance on May 26, 2006 at SBS‘s I-Concert performing the new single “U”, where it was also the group’s first return performance as a permanent group. Towards the end of 2006, Kyuhyun, along with Yesung and Ryeowook, was placed in Super Junior’s first subgroup, Super Junior-K.R.Y. The trio debuted on November 5, 2006 on KBS‘s Music Bank.
April 2007 car accident
In the early morning of April 19, 2007, just one month before Kyuhyun’s first anniversary in Super Junior, Kyuhyun with Super Junior members Leeteuk, Shindong, Eunhyuk, and two managers were all hospitalized due to a serious car accident when returning from the Super Junior Kiss the Radio show that night. The driver lost control of the vehicle as the van flipped over on its right side. Kyuhyun, who was sitting behind the driver’s seat when the accident occurred, was the most injured and had a fractured hip, pneumothorax from broken ribs, and facial scratches and bruises. He was slipping in and out of consciousness and was mute because of the shock. Kyuhyun spent 6 days in the ICU before he was moved to a regular hospital room. Kyuhyun also did not need the respiratory machine anymore to support his breathing, though it was said that he was only able to walk on his own one month after the accident. Kyuhyun was discharged on July 5, 2007 after 78 days.
