Artistry
Musical style influences and acting training
Han has said from childhood that she has been influenced by pop and R&B groups such as Fin.K.L, S.E.S. and Shinhwa. Han credits BoA as one of her major influences and idols. She also credits BoA's singing and dancing as influencing her to pursue a musical career. Additionally, she underwent formal vocal and acting training as a participant in the SBS talent show Superstar Survival.
Literary interests and authorship pursuits
In a 2024 episode of her former YouTube channel 궁금한선화 (Curious Sunhwa), Han shared that she has a passion for reading, often visiting bookstores to find comfort during stressful or frustrating periods. She also reflected on a solo trip to Croatia, describing it as a meaningful experience that allowed her to reconnect with herself and focus on personal growth. The trip inspired introspection, which led South Korean journalist and writer Kwak Jung-eun to suggest that Han write a book, indicating a potential future path as an author. Han stated that this is something she might pursue if the opportunity arises in the future.
Public image
During the early career of Secret, the group initially received limited attention following its debut before achieving greater recognition with subsequent releases. During this period, Han became known for an “airhead” (백치미) variety-show persona in television appearances, and was occasionally referred to in variety programs with playful labels such as “Baekji Sunhwa” and “Baekchi Sunhwa”. However, during a 2010 broadcast of Invincible Youth, Han clarified, in a humorous but also revealing manner, that the persona had been crafted as a concept by the CEO of TS Entertainment for Secret's promotional activities and that she had been instructed not to break character, prompting early public discussion about the agency's role in shaping her public image during the group’s formative years.
In 2015, after fellow Secret member Jung Ha-na referred to Han as being “dissatisfied with the world and prone to grumbling” during a variety-show discussion about the four members’ drinking habits, Han responded via Twitter, stating that what had been described as her having “a lot of complaints about the world” was instead her seeking advice and support from Jung and other members in the past, rather than expressing complaints, and that she felt burdened by the expectation of maintaining a manufactured variety-show image created by her agency, which did not reflect her actual personality. She added that Jung’s remarks were made without full context and that she responded publicly on Twitter to address potential misunderstandings. Group leader Jun Hyo-seong later stated that Han’s remarks had been misinterpreted and were not directed as criticism toward Jung. However, Han responded on Twitter disputing Jun's explanation, which led to renewed attention to her earlier statements about agency-imposed image expectations and her having sought advice and support from fellow members over an extended period. In a separate interview, Han stated that she understood that she could also be subject to such misunderstandings without full context, referring to so-called “actor’s disease,” a term used to describe actors being perceived as overly conscious of their image or behaving in a serious manner. Meanwhile, TS Entertainment said there was no internal discord and that the matter was not considered significant. Han subsequently left the group and the agency in 2016, making the 2014 album "Secret Summer" her final release with the group. TS Entertainment later became involved in multiple legal disputes with its remaining artists and was described by some media outlets as having abusive management practices, drawing attention to issues involving the agency’s management of both its remaining and former artists.
