Kim Jaejoong, better known by his stage names, Hero, Youngwoong Jaejoong (in South Korea) and Jejung (ジェジュン, Jejun?) (in Japan), is a Korean singer-songwriter, composer and occasional actor. He is a member of South Korean boy band TVXQ, known as Dong Bang Shin Ki in South Korea and Tohoshinki in Japan.

Hero was born as Han Jaejoon (한재준, 韓在俊) in Gongju, Chungcheongnam-do, South Korea. At a young age, Hero was given up for adoption by his birth mother to the Kims and his name was changed to Kim Jaejoong. When he was fifteen, he moved to Seoul by himself in order to take part in the auditions held by SM Entertainment. Life in Seoul proved to be hard for Hero and he had to take various odd jobs to come up with the ₩150,000 needed for the rent. He once took on a role as a soldier in the movie Taegeukgi Hwinallimyeo (태극기 휘날리며); with the money he acquired from the job he used the money to buy gum, which he sold to a female employee at a supermarket.

Along with the other members of TVXQ, Hero has starred in two televised programs, Banjun Theater and Vacation. He is set to feature in an episode of Japanese-Korean joint television drama, Heaven’s Postman (천국의 우편 배달부). It is about a mysterious man who delivers letters to heaven for people who can’t forget their deceased loved ones. His co-star is Han Hyo-joo..

Hero auditioned at SM Entertainment in 2001 and was accepted into the agency. On December 26, 2003, he debuted with TVXQ at a BoA and Britney Spears showcase. Apart from the group, Hero has worked on solo activities. He sang, "Insa" (인사 lit. Greeting), for the soundtrack of A Millionaire’s First Love. Hero collaborated with label-mates The Grace for the Japanese version of song "Just for One Day", which was featured on their fifth Japanese single and their debut album, Graceful 4. Hero also sang the solo track "Maze" which was for the fifth and final single in the Trick project, "Keyword/Maze".

Hero wrote and composed "Wasurenaide" (忘れないで, lit. Don’t Forget?) which included on TVXQ’s twenty-fifth single "Bolero/Kiss the Baby Sky/Wasurenaide", as the last two A-sides. The song later appeared on their fourth Japanese album The Secret Code, along with another song which he composed, "9095". For TVXQ’s fourth studio album, Mirotic, Hero wrote and composed Saranga Uljima (Don’t Cry My Lover) (사랑아 울지마). In 30 September 2009, he and Micky released a self-written duet, "Colors – Melody and Harmony/shelter", which was used as the image song for Hello Kitty’s thirty-fifth year anniversary.
