SinB/ Hwang Eun-bi (VIVIZ/former GFriend)

SinB's formative years as a trainee were spent under the guidance of Big Hit Entertainment, where she initially joined at the age of 12. Her training, which spanned over five years, was both rigorous and foundational, preparing her for the challenges of the K-pop industry. During this period, trainees like SinB underwent extensive practice sessions that began early in the morning and often extended into the late hours of the night, especially during monthly gradings.

The training regime at Big Hit was structured to not only enhance the artistic skills of the trainees but also to develop their personal attributes. This included classes in language, debate, songwriting, and producing. The emphasis was on building a versatile performer who could handle the pressures of the entertainment industry. Discipline was strict, with trainees living in dorms that, while comfortable, were part of a controlled environment designed to maximize their development potential. Interaction among trainees was limited, focusing them more on individual growth and preparation for potential debut.

SinB's early exposure to such a disciplined and comprehensive training environment played a crucial role in shaping her future career, laying the groundwork for her success with GFriend and later with VIVIZ.

SinB's ascent with GFriend was marked by significant milestones that propelled the group to stardom. Their breakthrough came with the song "Me Gustas Tu," which gained immense popularity after a viral fancam captured the members, including SinB, persevering through a performance despite repeatedly slipping on a wet stage. This display of resilience not only endeared them to the public but also revitalized the song's position on music charts, where it remained in the Melon Top 100 for 63 weeks, a record for an idol group in 2015.

Following this, GFriend released "Rough," which debuted at number two on the Gaon charts and later achieved the top position, holding it for two consecutive weeks. This track was not only a commercial success but also a critical one, securing GFriend's first music show win and multiple triple crowns, accumulating a total of 15 music show wins, the second-highest for a girl group song as of that year. This period in SinB's career with GFriend underscored the group's rising influence in the K-pop industry, marking their transition from promising newcomers to established stars.

The significant shift in SinB's career occurred on October 6, 2021, when she, along with former GFriend members Eunha and Umji, signed a contract with BPM Entertainment to debut as a trio. This new beginning was marked by the announcement of their group name, Viviz, just two days later on October 8, 2021. Viviz made their official debut on February 9, 2022, with their extended play, Beam of Prism, introducing a fresh musical direction.

The formation of Viviz was not just a career move but also a response to the sudden disbandment of GFriend. SinB revealed that the members were aware of their contract termination a month before it was publicly announced, leading to a deeply emotional period where they supported each other by sharing memories and watching fan videos. This emotional journey culminated in their decision to re-debut as Viviz, carrying forward their camaraderie and collective talent into this new chapter.

Viviz's name, an abbreviation for "VIVId dayZ," symbolizes their commitment to vividly expressing their unique colors to the world. The group's Korean name cleverly incorporates the final syllables of Eunha and SinB’s birth names (비) and Umji (지), reflecting their personal identities within the group. In a unique twist, the group decided not to appoint a formal leader, continuing to honor their former leader Sowon from GFriend, indicating a deep respect for their past while embracing their new journey.

SinB's career with GFriend and VIVIZ has been marked by notable accolades. With GFriend, she received numerous music show awards, which are primarily popularity awards reflecting fan engagement rather than musical quality. This recognition began in 2015, highlighting the intense support from fans and strategic marketing efforts, including aggressive YouTube ad campaigns that significantly influenced these awards.

In her later career with VIVIZ, SinB continued to make her mark. The group was nominated for the Seoul International Drama Awards in 2021 for their song "Like A Dream," which was featured as an Outstanding Korean Drama OST. Although they did not win, the nomination itself was a significant acknowledgment of their artistic contributions to drama soundtracks.

These awards and nominations are documented extensively, offering a glimpse into the competitive nature of the K-pop industry and the various factors, such as social media influence, that can affect the outcomes of these accolades.

SinB's involvement in media extends beyond her music career, showcasing her versatility as an entertainer. She made a memorable appearance on the children's television show "Larva And Friends In My Embrace," where she portrayed Shawing, the grasshopper fairy. This role not only highlighted her acting skills but also endeared her to a younger audience, many of whom recognize her from this show.

Her media presence was also evident during her time with GFRIEND. In an emotional revelation, SinB discussed the challenges faced during their final promotions for the song "Mago" in 2020. She expressed regret over not being able to perform to her full potential due to personal struggles with depression during that period. Furthermore, she shared that the members were not permitted to inform their fans of the impending disbandment until the official announcement, leading to a poignant moment where the members were seen crying during a live broadcast as they watched videos of fans cheering them on.

These appearances and candid shares not only reflect SinB's professional engagements but also her personal resilience and connection with fans, making her media appearances significant in understanding both her career and personal journey.

SinB, also known by her baptismal name Esther, has a diverse array of interests and unique traits that add depth to her public persona. She is known for her striking resemblance to Jessica Jung and has a notable background as a former child model, participating in shows like "The Fairies in My Arms". Her talents extend beyond singing and dancing; she is also skilled at acting and has expressed a fondness for bungee jumping and paragliding.

Her practical skills are highlighted by her ability to fix furniture and tools, making her the most handy member of her group. Additionally, SinB is recognized for her exceptional ability to learn choreography quickly, often taking the lead as the group's dance instructor. Despite her fearless persona, she has a strong aversion to horror movies, which she avoids due to easily getting scared.

An interesting aspect of her personality is her dislike of aegyo (acting overly cute), which contrasts with the often expected persona in K-pop. SinB's social circle includes notable friendships with other K-pop idols such as Astro's Moonbin and Twice's Dahyun, showcasing her well-connected presence in the industry.

Her religious faith is important to her, as indicated by her Roman Catholic affiliation and her baptismal name, Esther. SinB's zodiac sign is Gemini, and she shares her birthday with several other celebrities, which may intrigue fans who follow astrological signs.

SinB's influence in the K-pop industry is marked not only by her vocal and dance skills but also by the distinct stage presence and synchronization she demonstrated with GFriend. Critics have often highlighted GFriend's performances, which hinge on synchronized perfection, a feat not easily achieved by newly formed groups with diverse dance styles. Despite criticisms of their dance routines being overly simplistic, the group's ability to maintain clean, synchronized movements set them apart, making them a standout act in the competitive K-pop scene.

Moreover, SinB has been recognized for her dedication and resilience. During rehearsals, the complexity of their choreography often resulted in the members, including SinB, sustaining bruises from the intense practice sessions. This commitment was evident when SinB, despite the exhaustion from their grueling schedule, collapsed on stage during a live performance, showcasing her dedication to her craft and her group.

This level of performance and commitment has left a lasting impact on the perception of idol groups in K-pop, emphasizing the importance of synchronization and teamwork, which are now considered benchmarks for success in the industry. SinB's role in promoting these values through her performances with GFriend has not only influenced aspiring artists but also set a standard that many now strive to emulate.
