The relationship chart for See You at Work Tomorrow may look like a straightforward office romance at first glance, but a closer look reveals a workplace packed with complicated feelings, family expectations, friendship circles and a looming wedding that could shake up everything. While much of the early attention has naturally focused on the chemistry between Kang Si U and Cha Ji Yun, the drama's character map suggests there is far more happening inside Saeum Electronics than just another will-they-won't-they romance.
Leading the story is Seo In Guk as Kang Si U, a character expected to sit at the centre of the drama's romantic and professional tensions. Opposite him is Park Ji Hyun as Cha Ji Yun, whose position within the company places her directly in the middle of office politics, career ambitions and emotional complications.
Their relationship appears to be the main attraction, with the drama teasing a blend of workplace rivalry, awkward attraction and the sort of misunderstandings that somehow only happen between people who see each other five days a week and still fail to communicate properly.
However, viewers examining the official relationship chart have quickly noticed that Yun No A, played by Kang Mi Na, could become one of the drama's most interesting characters. No A works in the Product Planning Team at Saeum Electronics and is connected to several important figures across both her personal and professional life.
Unlike the uncertain romantic territory surrounding Si U and Ji Yun, No A appears to be moving towards a much more serious milestone. The chart openly hints that she and her boyfriend Kim Gu Won, portrayed by Yoon Jung Hoon, are preparing for marriage.
That small note saying "getting married soon" has already sparked curiosity among drama fans. In television romances, wedding plans rarely proceed without complications.
Between office deadlines, personal sacrifices and unexpected emotional twists, audiences know that a simple engagement announcement often translates into several episodes of stress, misunderstandings and family interference. It would almost feel suspicious if everything went smoothly.
No A's support system extends beyond her relationship with Gu Won. Her older sister Yun Da Ra, played by Yeom Seung Yi, has been given a dedicated place within the character map.
That detail alone suggests Da Ra could have a meaningful influence on No A's decisions. Korean dramas have long treated sibling relationships as emotional anchors, providing characters with the one person who can deliver brutally honest advice without getting blocked on social media afterwards.

Within the company, No A is closely linked to Sin Na Ri, portrayed by Lee Jae Yi. The two are entry-level colleagues who joined the company at the same time. Their friendship is likely to offer a realistic look at office life, where surviving endless meetings often creates stronger bonds than any corporate team-building exercise ever could.
As fellow newcomers, they may share career worries, workplace frustrations and perhaps a few observations about their managers that are best kept away from official emails.
The professional side of the story is equally crowded with influential figures. Kim Jung Young plays Han U Jin, the president of Saeum Electronics' DA Business Division, while Kim Hak Seon appears as executive director No Jin Cheol.
Together they represent the upper management layer that could create pressure for employees beneath them. Meanwhile, Park Ye Young's Choi Su Jin, manager of the Design Team, and Hong Woo Jin's Ko Yeong Sam, manager of Product Planning Team 1, add further workplace dynamics that may influence both promotions and personal relationships.
The supporting cast also expands the office ecosystem. Kang Gi Doong plays Product Planning Team 2 employee Jeon Gi Tae, while Kim Dong Young appears as Lee Seong Min, one of Kang Si U's closest friends.
Outside the office, Han Tae Ha joins the drama as Koo Seung Jun, guitarist of the band Autumn, introducing a creative presence that could provide a refreshing contrast to the structured corporate world.
Family remains another important piece of the puzzle. Yoo Sung Joo and Lee Ji Hyun portray Cha Yeong Muk and Nam Hye Gyeong, the parents of Cha Ji Yun. Their involvement suggests Ji Yun's personal life will be explored beyond the office walls.
Whether they become supportive parents or enthusiastic meddlers remains to be seen, but seasoned K-drama viewers already know parents rarely appear in relationship charts without eventually having opinions about somebody's life choices.
What makes See You at Work Tomorrow stand out is that it does not appear to rely solely on one central romance. Instead, the drama spreads its attention across different stages of adulthood.
One character is testing the waters of a new relationship, another is preparing for marriage, while others are simply trying to survive office life without losing their patience.
That balance could give the series a more relatable and grounded feel compared with workplace romances that focus entirely on one couple. Online reactions have been mixed but intrigued since the relationship chart was revealed.
Some fans are already invested in the potential romance between Kang Si U and Cha Ji Yun, while others believe Yun No A's storyline could end up stealing the spotlight.
Many viewers have also praised the chart for introducing multiple relationship layers rather than limiting the story to a single romantic arc. Others remain cautiously optimistic, joking that any character labelled "getting married soon" is practically carrying a giant warning sign in K-drama terms.
As anticipation builds, the character map suggests viewers should pay attention to more than just the obvious romantic leads. Between office politics, family influence, friendship dynamics and wedding preparations, See You at Work Tomorrow looks set to deliver a workplace comedy-romance filled with relatable chaos.
Which relationship are you most curious about, and do you think Kang Si U and Cha Ji Yun will become the drama's standout couple, or will Yun No A's journey end up being the real story everyone talks about?
