from Grokipedia
She Would Never Know is a South Korean romantic drama television series that premiered in 2021, centering on an office romance at a cosmetics company where a confident junior employee pursues his senior colleague amid professional and personal challenges. Starring Won Jin-ah as the ambitious marketer Yoon Song-ah and Rowoon (Kim Seok-woo) as the earnest rookie Chae Hyun-seung, the series explores themes of unrequited love, workplace dynamics, and self-discovery in a "noona romance" narrative. Supporting cast includes Lee Hyun-wook as Yoon Song-ah's ex-boyfriend Lee Jae-shin, Lee Joo-bin as her colleague and rival Lee Hyo-joo, and others such as Lee Kyu-han and Wang Bit-na. Directed by Lee Dong-yoon and written by Chae Yoon, the 16-episode series aired on JTBC from January 18 to March 9, 2021, on Mondays and Tuesdays at 9:30 p.m. KST. It is an adaptation of the 2017 web novel Senior, Don't Put on That Lipstick (Korean: Sunbae, Geu Lipstick Bareujimayo) by author Elise, which follows a similar story of romantic pursuit in a corporate setting. The drama received positive reception for its heartfelt portrayal of relationships and strong performances, particularly from the leads, earning an average rating of 7.4/10 on IMDb from over 2,700 users and 7.9/10 on MyDramaList from more than 26,000 users. It also garnered attention for its realistic depiction of the cosmetics industry and emotional depth, contributing to its popularity both domestically and internationally through streaming platforms like Netflix and iQIYI.

Background

Development

JTBC scheduled "She Would Never Know" as a Monday-Tuesday slot drama, capitalizing on the growing popularity of workplace romance genres in Korean television. The project was formally announced in May 2020 with the confirmation of leads Won Jin-ah and Rowoon, marking the beginning of public pre-production efforts. Supporting cast members, including Lee Hyun-wook and Lee Joo-bin, were added in August 2020, further solidifying the ensemble focused on office dynamics. Screenwriter Chae Yoon adapted the story from the 2017 web novel "Senior, Don't Put on That Lipstick" by Elise, emphasizing realistic depictions of corporate life and the nuances of an age-gap romance between colleagues. Revisions were made to enhance visual storytelling, transforming the novel's internal monologues into tangible scenes of workplace interactions and emotional growth suitable for the screen. Director Lee Dong-yoon, known for his work on "20th Century Boy and Girl," envisioned a grounded narrative that avoided fantastical elements, instead highlighting authentic character development and chemistry among the cast. Filming took place primarily in Seoul, utilizing urban locations to replicate the environments of a cosmetics company, including office sets and marketing team scenarios. Production adhered to strict COVID-19 protocols, such as mandatory testing and social distancing on set, which were standard for Korean dramas during the pandemic. Shooting was observed in public areas as late as November 2020, with principal photography wrapping in December 2020 to allow for post-production ahead of the January 2021 premiere. A key production challenge involved integrating corporate sponsorships from beauty brands into the narrative without compromising authenticity, as the story's cosmetics industry setting naturally lent itself to product placements while maintaining focus on interpersonal relationships and professional ambitions.

Source material

She Would Never Know is adapted from the web novel Senior, Don't Put on That Lipstick (Korean: Sunbae, Geu Lipstick Bareujimayo), written by Elise and first serialized on November 13, 2017. Published in book form by Graebooks, the novel spans 42 chapters and centers on themes of unrequited workplace romance within a cosmetics company, where the protagonist navigates emotional complexities in her professional environment. The source material gained significant traction on platforms like Naver Series, where it holds a 9.2 rating from readers, and KakaoPage, attracting readers before the drama adaptation boosted its visibility further. Its exploration of mature relationships and office dynamics contributed to its appeal among romance genre enthusiasts. A webtoon version, adapted for visual storytelling by writer Cafelatte and illustrator JINHA, premiered on Naver Webtoon on January 4, 2021, and concluded on December 12, 2021, aligning with the drama's broadcast schedule. This adaptation features 50 episodes, emphasizing the novel's romantic tension through illustrated panels and character expressions. While faithful to the core narrative of the novel, the drama condenses several subplots to accommodate its 16-episode structure, introduces enhanced visual depictions of cosmetics marketing scenarios not as prominent in the text, and modifies arcs for supporting characters to improve pacing for television audiences.

Cast and characters

Main roles

Yoon Song-ah, portrayed by Won Jin-ah, is an ambitious and professional cosmetics marketer at KLAR Cosmetics, known for her perfectionist and workaholic nature. She is deeply passionate about her career, driven by aspirations to launch her own brand, while navigating family pressures from her widowed mother, who relies heavily on her emotionally and financially, and a younger brother who adds to her sense of responsibility. Song-ah enters the story in a toxic, secret relationship with her superior, marked by imbalance and emotional strain that influences her guarded approach to younger suitors. Chae Hyun-seung, played by Rowoon, serves as an idealistic and dashing junior marketer who joins Song-ah's team, immediately drawn to her as his senior colleague. His persistence in pursuing a romantic connection stems from genuine admiration, tempered by vulnerability rooted in past experiences, including a previous long-distance relationship that ended due to challenges and family dynamics involving two protective older sisters who have endured personal hardships. Hyun-seung's traits—brightness, adorability, and a serious demeanor beneath his charming exterior—fuel his determination to transform their professional mentorship into love, despite the age gap. Lee Jae-shin, enacted by Lee Hyun-wook, is Song-ah's older boyfriend and the ambitious director of the marketing team, whose controlling tendencies manifest in their imbalanced relationship, often prioritizing his own needs while keeping their affair hidden to avoid workplace scrutiny. Inwardly pained and reserved, his backstory reveals a difficult past that contributes to his manipulative behaviors, including entanglements that complicate office dynamics. Jae-shin's professional drive mirrors Song-ah's, but his subtle expression of emotions through restrained gazes and actions underscores his complex motivations. Lee Hyo-joo, brought to life by Lee Joo-bin, is the wealthy granddaughter of the cosmetics company founder and a rising photographer, initially presenting a hard exterior that hides her soft heart and adds layers of romantic rivalry through her obsessive engagement to Jae-shin. Her unstable traits evolve as she confronts privilege and emotional dependency, intersecting with the central romance by heightening tensions around Jae-shin's divided loyalties and indirectly challenging Hyun-seung's pursuit. Hyo-joo's backstory of familial expectations amplifies her role in the narrative's exploration of love and self-growth. The dynamics among these characters center on an age-gap office romance, where Song-ah and Hyun-seung's mentorship evolves into mutual affection amid professional challenges, contrasted by Jae-shin's possessive hold and Hyo-joo's rival claims that test boundaries and foster personal development.

Supporting roles

The supporting roles in She Would Never Know enrich the central narrative by underscoring themes of familial bonds, workplace camaraderie, and subtle rivalries, often serving as catalysts for the protagonists' emotional and professional development without dominating the storyline. These characters interact with the leads to highlight conflicts around romance, career ambitions, and personal insecurities in the competitive cosmetics industry. Kim Ga-young, portrayed by Kang Hye-jin, is Yoon Song-ah's steadfast colleague and friend, a department store salesperson who injects levity and unwavering support into Song-ah's tumultuous personal life and office challenges. Her interactions provide comic relief during tense moments, such as advising Song-ah on relationships and workplace stresses, thereby facilitating subplots on female friendship and resilience. The Chae family members offer pivotal emotional grounding for Chae Hyun-seung's arc, emphasizing sibling support amid his unrequited affection for Song-ah. Chae Ji-seung, played by Wang Bit-na, is Hyun-seung's poised older sister and CEO of a wedding dress design firm, whose elegant demeanor and practical wisdom guide her brother through romantic setbacks and family discussions. Complementing this, Chae Yeon-seung, enacted by Ha Yoon-kyung, serves as the middle sister and a devoted housewife, contributing heartfelt, everyday perspectives on marriage and loyalty that subtly influence Hyun-seung's growth. Together, these roles amplify family dynamics as a source of stability, contrasting the leads' professional uncertainties. Within KLAR Cosmetics, key figures shape the career-driven tensions central to the plot. As the company's director and heir, Lee Jae-woon, brought to life by Lee Kyu-han, embodies relaxed competence and wit, influencing team hierarchies and injecting humor into subplots of corporate growth and interpersonal rivalries among colleagues. Additional team members, such as Kim Min-sung (Kim Seo-ha) and Lee Se-rim (Park Han-sol), round out the ensemble by depicting collaborative efforts in marketing campaigns, underscoring themes of collective professional evolution. Guest appearances, including brief promotional cameos by actors like those in ensemble office scenes, further enhance the drama's realism by illustrating the broader industry network, though they remain peripheral to the core conflicts. Overall, these supporting characters bolster the main storyline by weaving in layers of relational depth, ensuring the focus stays on the leads' romance while exploring ancillary themes of solidarity and ambition.

Theme songs

The primary theme song for She Would Never Know is "Lean On Me" (나는 그래) by Kim Jong Wan of NELL, a melancholic ballad that captures the essence of unrequited love and emotional support central to the series' romantic narrative.

Release and reception

Domestic broadcast and ratings

She Would Never Know aired on JTBC from January 18, 2021, to March 9, 2021, occupying the network's Monday-Tuesday time slot at 9:30 p.m. KST. The series comprised 16 episodes, each running approximately 70-80 minutes, and concluded on schedule without any extensions. According to Nielsen Korea, the premiere episode recorded a nationwide viewership rating of 2.024 percent, marking a modest start for the cable drama. Ratings fluctuated throughout the run, peaking at 2.427 percent for episode 3 on January 25, 2021, before settling into the low 2 percent range for most episodes. The series finale on March 9 achieved 1.728 percent, with an overall average of 1.846 percent—figures considered underwhelming compared to broadcast network competitors but typical for JTBC's cable slot during a period dominated by high-profile SBS airings like The Penthouse: War in Life, which consistently exceeded 20 percent in early 2021. Viewership was influenced by intense competition from established broadcast dramas on SBS and KBS, which drew larger audiences during prime time. However, the series benefited from lead actor Rowoon's rising popularity and dedicated fandom from his SF9 idol days, contributing to steady interest despite the modest numbers. The drama's performance sustained JTBC's Monday-Tuesday lineup, transitioning to the follow-up series Lost starting March 22, 2021.)

International distribution

She Would Never Know became available on Netflix globally starting in July 2022, accessible in over 190 countries where the platform operates. The series premiered on the service in regions such as the United States on July 10, 2022, and the United Kingdom on July 8, 2022, allowing international audiences to stream all 16 episodes with English subtitles and audio options in select languages. In China, the drama aired simultaneously with its South Korean broadcast on iQIYI beginning January 18, 2021, featuring Chinese subtitles and contributing to its early international exposure in the region. Viu also distributed the series across Southeast Asia, providing subtitles in multiple local languages to cater to viewers in countries like Indonesia, Malaysia, Philippines, and Thailand. The show's international popularity surged on Netflix, ranking in the global non-English TV top 10 during the week of July 11-17, 2022, with 10.4 million viewing hours. It achieved top 10 status in nine countries, including Indonesia, Philippines, Malaysia, Taiwan, Thailand, Vietnam, Qatar, Maldives, and Sri Lanka. This performance highlighted its appeal in Southeast Asia and other Asian markets, where it resonated with audiences through its office romance narrative.

Critical response

She Would Never Know received mixed reviews from critics, who praised its realistic depiction of office romance and strong lead performances while critiquing its predictable plot and occasional pacing issues. The series holds an average rating of 7.4 out of 10 on IMDb based on user reviews, reflecting appreciation for its emotional authenticity, and 7.9 out of 10 on MyDramaList, where viewers highlighted its relatable character dynamics. However, some outlets noted the story's reliance on familiar tropes, such as workplace hierarchies and age-gap romance, which led to a sense of familiarity over innovation. Critics lauded the performances of leads Won Jin-ah and Rowoon, with Won Jin-ah earning acclaim for portraying Yoon Song-ah's emotional depth as a resilient career woman navigating personal and professional challenges. Rowoon's debut in a major leading role was particularly highlighted for his charming and nuanced depiction of Chae Hyeon-seung, blending vulnerability with determination in a breakout performance that showcased his potential beyond idol acting. Supporting cast members, including Lee Hyun-wook, were also commended for adding layers to the ensemble, though some reviews pointed out that the chemistry between the leads occasionally felt restrained. Thematically, the drama was appreciated for addressing toxic relationships and workplace dynamics, particularly through Song-ah's experiences with a manipulative ex and gender-based power imbalances in a cosmetics firm, offering insights into modern feminism and professional resilience. Reviewers noted its exploration of emotional maturity in romance, contrasting idealized love with real-world complications like age differences and career pressures. However, criticisms arose regarding an excess of melodrama in handling these elements, with some scenes portraying possessive behaviors as romantic rather than problematic, potentially undermining the feminist undertones. Media coverage in international outlets like the South China Morning Post emphasized the series' blend of romance and social commentary, though it faulted the execution for lacking depth in secondary plots and product placements that disrupted immersion. Similarly, The Review Geek described it as a solid but unremarkable entry in the genre, praising its grounded approach while suggesting tighter pacing could elevate its impact. Overall, the drama was often positioned as an accessible watch for fans of mature romances, with retrospective mentions in 2021 coverage labeling it an underrated entry amid busier releases.
