Eru ( 이루 born July 5, 1983) is the stage name of South Korean singer Jo Sung Hyun. He is the son of veteran trot singer, Tae Jin Ah. Eru attended Berklee College of Music in Boston, U.S.. He entered the k-pop scene himself during a break from Berklee College of Music.

Before releasing his first album, Eru underwent two years of strict training. Eru's debut album included works from musicians such as Joo Young Hoon, Lee Hyun Jung, the composer of Big Mama's "Break Away". And vocal trainer No Young Joo, who trained BoA, Fly to the Sky, and Lee Soo Young. Also a 100-member string orchestra participated in his debut album.

Black Glasses gained popularity among young people and topped on- and offline charts. This song has won many awards, including Jukeon's song of the month (October of 2006) and SBS's Bonsang Award.

Debut
Eru's Black Glasses music video features Kim Hyun Joong of SS501 and Lee Young Ah. After the success of Black Glasses, Eru released his second single, White Snow in which he composed himself. White Snow continued the success of Eru's career, reaching #1 on various online charts and gaining the same popularity as Black Glasses had. Aside from his own music video, Eru appeared in female singer Magolpi's debut music video where his role is as a composer along with six other Korean artists, including Kim Jang Hoon, Park Joon Hyung of G.O.D., Micky YooChun of TVXQ, and Hee Chul, Kang In, and Shin Dong of Super Junior.

In March of 2007, Eru received an offer to appear in a Japanese movie titled "Three Tattoos". Eru's agency stated that it is quite tempting since the movie is being directed by Sukimori Hitomi and will likely be exported overseas. Eru's agency also stated that Eru may reject the offer as he has yet to establish himself in Korea as an artist.

Eru released his 3rd album “eru returns” on September 9, 2007.
