Raina

Oh Hye-rin (Korean: 오혜린), known professionally as Raina (레이나), is a South Korean singer. She is best known as a former member of the girl group After School and its sub-unit Orange Caramel. Raina debuted with After School in November 2009 on the single "Because of You," which became a defining hit of the group's career. Her high-pitched, powerful vocals made her the group's main vocalist and a standout performer. She later debuted as a soloist in 2014 with the ballad "You End, And Me." Raina also found success as a collaborator, notably with rapper San E on the 2017 duet "A Midsummer Night's Sweetness," which won several awards. After After School's hiatus, she transitioned into musical theater, taking roles in productions like "The Three Musketeers" and "Mefisto." As of 2026, Raina continues to perform as a solo singer and musical actress, maintaining a loyal fanbase that appreciates her vocal talent and warm, down-to-earth personality. She is widely regarded as one of the most skilled vocalists of her generation in K-pop.[edit]

Raina was born on May 7, 1989, in Ulsan, a major industrial city in southeastern South Korea. From a young age, she showed a strong passion for music, often participating in school singing contests. She attended Ulsan Art High School, where she majored in vocal music, honing her technical skills. She later studied at Myongji University as a vocal music major. Her first attempt at joining an entertainment agency did not work out, but she persevered and successfully auditioned for Pledis Entertainment. Before joining After School, she trained under Pledis for a period, preparing to be added to the group's evolving lineup. Her big break came in late 2009 when she was chosen to join After School just before the release of their third single, "Because of You."[edit]

Raina debuted as a member of After School with the November 2009 single "Because of You," which became a massive hit and established the group's signature sexy and powerful concept. In 2010, she became a member of the sub-unit Orange Caramel alongside Nana and Lizzy. Orange Caramel's quirky, retro, and cute concept contrasted sharply with After School's image and produced hits like "Magic Girl" (2010), "A~ing♡" (2011), and "Catallena" (2014). Raina debuted as a soloist in September 2014 with the digital single "You End, And Me," a ballad showcasing her vocal range. In 2017, she collaborated with rapper San E on "A Midsummer Night's Sweetness," which topped charts and won the Melon Hot Trend Award and Mnet Asian Music Award for Best Collaboration. She released the solo single "It's Okay" in 2019. After After School's disbandment in 2019, Raina left Pledis Entertainment in 2021. Since then, she has focused on musical theater, performing in productions like "The Three Musketeers" and "Mefisto." As of 2026, she continues to perform occasionally as a solo singer.[edit]

Raina is known for her cute, feminine, and sometimes quirky aesthetic, especially during her Orange Caramel days. In her solo work, she adopts a more mature, ballad-singer image. The media portrays her as a talented but private and humble vocalist. Her social media presence mixes professional updates with personal, often cute photos of herself and her dog. Fans appreciate her down-to-earth personality and powerful vocals. Her official solo fandom name is not widely publicized; fans are often included in the broader After School fandom, Playfulz.[edit]

Raina commands a steady, global audience anchored by her tenure as the main vocalist of After School and her subsequent solo career. While she remains a recognizable figure in South Korea and among K-pop enthusiasts worldwide, iFANN's Global Fame Engine has evaluated this person, but they do not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). This absence from the leaderboard indicates that while her cultural footprint is significant within specific demographics, it does not yet reach the threshold required for a numerical ranking against the general population. The fanbase supporting Raina lacks a formally registered, standalone name; unlike groups with dedicated sub-fandoms, her supporters identify simply as fans of "Raina" or operate under the broader umbrella of the group's former fandom, ASB. This community is characterized by high loyalty and resilience, having actively campaigned for reunions during the group's hiatus and maintaining interest through her musical theater work. A defining interaction between the artist and her audience occurred when Raina publicly recounted a dramatic incident from her early days involving a run-away from their dormitory with fellow member Nana. By sharing this vulnerable story, she fostered a deeper emotional bond with fans who grew up watching her career, validating the struggles of her peers and reinforcing the nostalgic connection that defines her public image.[edit]

Raina's stage name was chosen by her company and means "a lot of love" in Korean. She is known for her extremely high-pitched and powerful vocals, often praised as one of the strongest vocalists in After School. She is a close friend of fellow After School member Nana. Despite her fame, she has remained remarkably private about her personal life, with no confirmed romantic relationships. She is approximately 167 cm (5'6") tall. Raina's Instagram handle is @raina_57 with over 200,000 followers, her Twitter is @raina57 with over 100,000 followers, and her YouTube channel @raina57 has around 50,000 subscribers. Fans still retell the legendary story of how Raina and Nana ran away from their dormitory during the intense pressure of their debut era under Pledis Entertainment, an event that became part of the group's folklore. Another iconic moment in her career involves the 2013 promotion of "First Love," where the group performed pole dancing and adopted a mature aesthetic that challenged traditional K-pop norms at the time. The reunion of the After School members in November 2019 stands as a major milestone, officially reviving the group's mythology and allowing Raina to reconnect with her legacy alongside her former colleagues.[edit]

Raina was raised in Ulsan, South Korea. Details about her parents and siblings have not been publicly disclosed, as she keeps her family life private. As of 2026, she lives in South Korea and has a pet dog named Bbang, which means "bread" in Korean. She has not shared information about her current household beyond her pet.[edit]

Raina is closely associated with her fellow After School and Orange Caramel member Nana, with whom she shares a close friendship. She collaborated frequently with rapper San E, most notably on the hit "A Midsummer Night's Sweetness." Former After School leader Kahi served as a mentor figure. Raina was under Pledis Entertainment from her debut until 2021.[edit]

Raina has kept her romantic life extremely private. As of 2026, there are no publicly confirmed relationships, engagements, or marriages. She has not been linked to any known partners through credible reports. She is currently reported to be single.[edit]

Heading into 2026, iFANN currently estimates Raina's net worth to be $2 Million. Her primary sources of income include earnings from After School and Orange Caramel album sales, tours, and endorsements during their active years. She also earns from solo music sales and streaming revenue. Her musical theater roles provide additional income, as do occasional variety show appearances and events. She may have real estate holdings in South Korea, though details are not public.[edit]

Raina has won two major awards as a solo artist. In 2017, she won the Melon Music Award for Hot Trend and the Mnet Asian Music Award for Best Collaboration, both for her duet "A Midsummer Night's Sweetness" with San E.[edit]
