Pre-debut
Donghae was born in Mokpo, Jeollanam
on 15 October 1986. Donghae initially wanted to become an athlete, but under
the influence of his father, who once desired to become a singer, Donghae
decided to train himself to become a singer.
In 2001, Donghae signed a contract
with SM Entertainment soon after he jointly won the Best Outward Appearance
award with future band mate Sungmin
on the company's third annual SM Youth Best Contest. Under SM
Entertainment, Donghae was put in singing, dancing, and acting lessons, and was
then recruited into a five-member boy band Smile, with future band mate Leeteuk,
but the idea was soon dropped.
In 2004, Donghae, along with Leeteuk
were put into another boy band and formed Super Junior with ten other trainees.
The group later became known as Super Junior 05, the first generation of
a rotational music group, Super Junior. In November 2005, several days
before the group's debuted, Donghae made a brief appearance at SBS's Shin Dong-yup's There Is There Isn't panel.
2005-2006:
Debut with Super Junior
Donghae officially debut as part of
12-member project group Super Junior 05 on 6 November 2005 on SBS's music programme Popular Songs, performing their first single, "TWINS (Knock Out)". Their debut album SuperJunior05
(Twins) was released a month later on 5
December 2005 and debuted at #3 on the monthly MIAK K-pop album charts.
In March 2006, SM Entertainment
began to recruit new members for the next Super Junior generation. However,
plans changed and the company declared a halt in forming future Super Junior
generations. Following the addition of thirteenth member Kyuhyun,
the group dropped the suffix "05" and became officially credited as
Super Junior. The re-polished group's first CD single "U" was released on 7 June 2006, which was their most
successful single until the release of "Sorry, Sorry" in March 2009.
Donghae made his acting debut in
Super Junior's horror documentary Mystery 6, broadcasted in early 2006.
The documentary surrounds Donghae and his peculiar ability to see and feel
ghosts. In August 2006, Donghae played the role of a human turned cyborg in the
Korean version of BoA's
music video drama, "Key of Heart", his first lead appearance in a music video.
