Early life

Raina, whose birth name is Oh Hye-rin, is a South Korean singer born on 7 May 1989 in Ulsan. Her schooling included Mu-geo Elementary School, Sungkwang Girls' High School and Korea Art High School. Before her debut she tried out with JYP Entertainment as a rapper and then joined Pledis Entertainment. She also worked as a barista at a Coffee Bean & Tea Leaf shop, auditioned for the Mnet competition Superstar K and studied at the SM Academy.

Career

Raina debuted in November 2009 as a member of the girl group After School, joining for the release of the group's single "Because of You", which reached number one on the Gaon Digital Chart and earned a "triple crown" on the SBS music programme Inkigayo. On 18 June 2010 she made her debut in Orange Caramel, a sub-unit of After School, performing "Magic Girl" on KBS Music Bank. She was also part of A.S. Red & Blue in 2011. By the listings used here she belonged to After School from 2009 to 2015 and to Orange Caramel from 2010 to 2016.

Alongside her group activity she began writing lyrics. She wrote the words to the Orange Caramel songs "Still..." and "In this Place", and to the After School songs "Love Love Love" and "Timeless". Her first solo recording was a song for the soundtrack of My Shining Girl, released in February 2012.

On 12 June 2014 she released the R&B duet "A Midsummer Night's Sweetness" with the rapper San E. The song topped the major South Korean music charts soon after release and placed fourth on the year-end Gaon Digital Chart. That October she became the first member of After School to debut as a solo artist, with the single "Reset", whose title track was "You End, and Me" and whose b-side was "Repertoire". Her second digital single, "I Don't Know", followed on 24 November 2015, and in June 2016 she and San E released a second duet, "Sugar and Me".

Soundtrack work became a regular part of her output. In June 2017 she released "When Rain Falls" for the MBC drama Lookout, with her bandmate E-young taking part in the lyrics, composition and arrangement. She then issued the single album Loop, whose title track features Aron of NU'EST.
