사내맞선 (Business Proposal) — Office Korean from Korea's Most-Watched Rom-Com

사내맞선 made Korean office life feel warm, awkward, and endearing all at once. Here are the phrases from the show that double as real workplace Korean.

A blind date. A disguise. A CEO who sees through everything anyway.

Business Proposal (사내맞선) became one of Netflix's most-watched Korean dramas for a simple reason: it's genuinely funny, warmer than it has any right to be, and set entirely in a Korean office that Koreans recognized immediately.

For learners, it's a goldmine. The workplace vocabulary is real. The power dynamics are real. And the way characters navigate formality while slowly falling for each other — that tension is very, very Korean.

The title

사내맞선

💡 사내 (社內) = within the company, 맞선 = a formal blind date arranged by others. The premise: a woman fills in for her friend at a blind date and discovers the man is her CEO.

Key words from the show

회의

Romanizationhoeui

Meaningmeeting / conference

💡 The most-used word in any Korean office drama. 회의 있어요 (I have a meeting) is the fastest way to exit any conversation professionally.

보고서

Romanizationbogoseo

Meaningreport / written report

💡 The document every Korean office worker dreads submitting and every boss requests urgently. In 사내맞선, the heroine's 보고서 mishaps kickstart half the plot.

야근

Romanizationyageun

Meaningovertime / working late

💡 야 (夜) = night, 근 = work. Korean office culture is famous for 야근. In the show, characters frequently stay late — often at the same time as the person they're trying to avoid.

대표님

Romanizationdaepyonim

MeaningCEO / president (honorific)

💡 대표 = representative/head, 님 = honorific suffix. In Korean workplaces, people address each other by title, not name. Knowing titles is knowing the social map.

Cultural note

사내맞선 captures something specific about Korean workplace culture: hierarchy shapes everything, including how people speak to each other.

In Korean offices, the title you hold determines how you're addressed, where you sit, who pours whose drink at dinner, and whether you're allowed to leave before your senior does. The drama takes this structure and makes it the central romantic obstacle — two people who cannot simply be people around each other because one of them signs the other's paycheck.

The reason it resonates so widely is that Korean audiences recognized every careful bow, every switch between formal and informal speech, every meeting where someone is clearly nervous underneath the professionalism.

For learners: the show is excellent for hearing formal (존댓말) and casual (반말) Korean side by side. Characters shift between them as closeness develops — a real-time signal of where the relationship stands.
