Ji In

Ji In is a South Korean singer, actress, and songwriter. She originally debuted as a main vocalist of the K-pop girl group Girl's Day in 2010, but left the group after two months. She later transitioned to trot music under the stage name Jang Hyeri and continues to perform and act. [edit]

Ji In was born on March 13, 1992, in Chuncheon, South Korea. She attended Anyang Art High School, where she developed her skills in music and performance. Her hobbies include cooking, listening to music, and watching movies. She was scouted by Dream T Entertainment and became a trainee, eventually being selected as one of the five original members of Girl's Day. The group was formed in 2010, and Ji In prepared for her debut alongside Sojin, Minah, Jisun, and Jihae. [edit]

Ji In debuted with Girl's Day on July 9, 2010, with the mini-album Girl's Day Party 1 and lead track "Tilt My Head." However, in September 2010, just two months after debut, she left the group to focus on acting, along with fellow member Jisun. She was replaced by Hyeri, who later became the group's most famous member. On December 26, 2012, Ji In collaborated with former Girl's Day member Jihae to release a song titled "Loving Day." She then joined the group Bebop in 2014, remaining until 2016. After leaving Bebop, she reinvented herself as a trot singer under the stage name Jang Hyeri, also working as an actress and songwriter. She appeared on the music variety show I Can See Your Voice. [edit]

As a former member who left Girl's Day very early, Ji In has a relatively low public profile. She is known primarily among dedicated Girl's Day fans as one of the five original members. Her transition to trot music under a new stage name reflects a reinvention that few K-pop idols attempt, giving her a niche identity in the Korean music scene. [edit]

Ji In has never cultivated a formal, standalone fandom bearing her own name. As one of the five original members who departed Girl's Day in 2010 before the group achieved its massive commercial breakthrough, she did not spark the organized campaigns, streaming projects, or birthday tributes that define modern idol fanbases. Her transition from a brief K-pop tenure to an acting career and later a trot music persona under the stage name Jang Hyeri occurred outside the spotlight of dedicated fan clubs. While the general Girl's Day community, known as "Daylight," remembers her contribution to the group's early history, no specific rituals or inside jokes have emerged that are exclusive to Ji In herself. Dedicated observers often discuss the confusion between her identity and that of fellow ex-member Hwang Ji-seon, but this remains a niche topic among historians rather than a driver of active fandom engagement.

Regarding her global standing, iFANN's Global Fame Engine has evaluated Ji In, but she does not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). She is unranked. This status reflects her current position as a figure with a niche presence in the Korean music scene rather than a globally dominant star. The evaluation considers media coverage, search signals, and consumption patterns worldwide, yet these metrics do not currently place her on the official leaderboards.[edit]

Ji In left Girl's Day just two months after their 2010 debut, marking the shortest tenure of any original member before being replaced by Hyeri. She later adopted the stage name Jang Hyeri to pursue a career in trot music, a genre shift that few K-pop idols attempt. During her musical journey, she participated in the variety show I Can See Your Voice and served as a member of the group Bebop from 2014 to 2016. Her blood type is O. Among long-time fans, a persistent story circulates about the confusion between her identity and that of fellow ex-member Hwang Ji-seon (Jisun), who also pursued a solo singing career. While some sources incorrectly conflate the two, dedicated observers clarify that Ji In focused on acting after leaving the group, whereas Jisun became the trot star Jang Hyeri. This distinction has become a minor piece of trivia lore, often cited by historians of the group to correct misconceptions found in older articles. Another enduring detail is the contrast between her brief, high-profile debut and her later, more niche presence in the trot industry, a duality that defines her unique place in the K-pop timeline.[edit]

No publicly available information about Ji In's parents or siblings is confirmed. She keeps her family life private. [edit]

Ji In was a member of Girl's Day alongside Sojin, Minah, Jisun, and Jihae. She later collaborated with Jihae on the song 'Loving Day.' Her replacement in Girl's Day was Hyeri, who became the group's most famous member. [edit]

No public romantic relationships for Ji In are documented in available sources. As of 2026, her relationship status is unknown. [edit]

Per iFANN's editorial analysis, Ji In's net worth is estimated at around $1 million as of 2026. This figure reflects her earnings from her music career as a trot singer performing under the name Jang Hyeri, which includes live performances, songwriting royalties, and occasional acting roles. Earlier income generated during her brief stint with Girl's Day and her subsequent time in the group Bebop also contributed to her financial accumulation. Compared to the current members of Girl's Day, her public profile remains lower, a factor that is clearly reflected in this modest net worth estimate.[edit]
