Sunggyu

Kim Sunggyu (Korean: 김성규; Chinese: 金聖圭; Japanese: キム・ソンギュ; born April 28, 1989)(24 years and 25 years in Korea), more commonly known as Sunggyu (officially spelt as Sungkyu), is a South Korean idol, singer and dancer. He is the leader and main vocalist of the Korean boy group Infinite under Woollim Entertainment. He made his debut as a solo artist on November 7, 2012.

Kim Sunggyu was born on April 28, 1989 in Jeonju, South Korea. He attended Jeonju National University High School and was in the school rock band called "Beat." When Sunggyu first told his parents about his dream to become a singer, they rejected it because they wanted him to have a normal life and told him they'd rather he leave the house instead. He continued to practice in secret and came to Seoul alone to pursue his dreams after graduating from high school. In 2007, he auditioned for SM Entertainment but failed to make the cut, and auditioned once more in 2008 only to fail again. Due to his admiration for rock band Nell, he initially auditioned at Woollim Entertainment under the recommendation of Nell's manager whom he'd met coincidentally at the cafe where he worked at part-time. With a hurting stomach, Sunggyu went to his audition and lightly threatened them by saying, "If you don't pick me, I'm going to bother you forever." Afterwards he rushed to the hospital immediately and got an appendectomy. On the day of his release, he received the notification that he had passed his audition. Originally intending to pursue rock music in a band, Sunggyu instead became a trainee for the dance group Infinite, of which he would later assume the positions of Leader and Main Vocalist. Despite being criticized by his school friends, he believed that it was an opportunity nonetheless and persisted. In 2010, Sunggyu finally made his debut with Infinite on June 9.
On February 15, 2013 Sunggyu graduated from Daekyung University's Practical Music program and received along with members L, Sungyeol, Hoya, and Dongwoo, the 'Proud Daekyung University Student award' in hopes that the group would continue to grow and bring prestige to the school. The members had been accepted through a special screened admittance in early 2011.
