1. Why This Drama Is Getting Attention
Viewers come for romance, but stay for chemistry. The office setting feels familiar, yet the emotions are quiet. The See You at Work Tomorrow cast helps fans understand the story fast. Seo In Guk new drama 2026 is about work pressure, fatigue, and slow change. I checked broadcaster information and cast references before writing this guide. This guide is for readers new to Korean workplace culture.
2. See You at Work Tomorrow cast Guide: Who Plays Who
Kang Si Woo is a strict manager who values order. Cha Ji Yoon is a seventh-year office worker who looks capable but feels burned out. Their contrast creates romantic tension. The See You at Work Tomorrow cast also shows different sides of office life, from ambition to awkward past ties.
2.1. Kang Si Woo (Played by Seo In Guk)

※ Position: Manager at Saewoom Electronics, DA Division
Kang Si Woo is known as the “Three-No Man.”
No smile. No people. No sorry.
He rarely laughs, rarely gets close to others, and rarely apologizes first.
Even when someone makes a serious mistake, he does not shout.
Instead, he delivers a short, cold truth that cuts even deeper.
But his tightly controlled work-mode life slowly begins to crack after Cha Ji Yoon enters his routine.
2.2. Cha Ji Yoon (Played by Park Ji Hyun)

※ Position: Senior employee at Saewoom Electronics, DA Division
Cha Ji Yoon is smart, fast, and highly capable at work.
But when office hours end, she leaves without hesitation.
After seven years in the workplace, she has learned that doing her best is not always the best answer.
She is a realistic office worker who knows how to survive by choosing the “good enough” option.
However, her peaceful work life starts to shake when Kang Si Woo suddenly steps into her world.
2.3. Yoon No Ah (Played by Kang Mi Na)

※ Position: Employee at Saewoom Electronics, Product Planning Team 1
Yoon No Ah is pretty, smart, and a little clumsy.
That unexpected gap makes her even more charming.
For seven years, her boyfriend Gu Won has always been her number one priority.
She believed everything would be fine once they got married.
But on the day her relationship begins to fall apart, a mysterious man with purple hair appears in front of her.
2.4. Jo Ga Eul (Played by Choi Kyung Hoon)

※ Role: Vocalist of the band “Gaeul,” Ji Yoon’s college friend and first love
Jo Ga Eul is the complete opposite of Kang Si Woo.
He is a free spirit who does not hold on to worries, obsession, or regret for too long.
Whenever life gets complicated, he simply smiles and says, “It’s okay.”
He knew Ji Yoon had feelings for him, but he kept leaving and coming back without warning.
Then, after returning from Australia, he suddenly confesses to her and ends her eight-year one-sided love.
2.5. Lee Jae In (Played by Won Gyu Bin)

※ Role: Surfer boy
Lee Jae In has a mysterious aura, partly because of his purple hair and partly because of his relaxed expression.
He grew up in a wealthy and free environment, with enough support to explore whatever he wanted.
That freedom, mixed with a quiet sense of loneliness, shaped his musical talent.
He can seem rude because he is too honest, and his curiosity often leads him into strange situations.
But the moment he first sees Yoon No Ah, he cannot help wondering why someone like her looks so sad.
3. Story Explained Without Heavy Spoilers
The problem is simple: many office K-dramas can look predictable. This one uses familiar ingredients, including a tired employee, a difficult boss, and unspoken feelings. The solution is to watch the details, not only the romance. Seo In Guk new drama 2026 feels easy to enter because the conflict is personal and clear.
