At the heart of Tempest is Seo Mun-ju, a brilliant diplomat who has spent her career building peace across borders. But her world unravels when a shocking assassination attempt drags her into the dangerous undercurrent of global politics. No longer just a voice at the negotiation table, Mun-ju suddenly becomes a target — and survival means stepping into a world she was never meant to face.
Enter Baek San-ho, a mercenary with a complicated past and a reputation for living in the shadows. At first, Mun-ju and San-ho clash — she’s cautious, principled, and used to diplomacy, while he’s reckless, battle-hardened, and mistrustful. But as the conspiracy widens, the two are forced to rely on each other. Together, they race against time to expose the truth behind the hidden power players who are pulling the strings.
The drama doesn’t just stop at politics — it dives deep into themes of loyalty, sacrifice, and the blurred line between justice and survival. Every mission brings new betrayals, unexpected allies, and moments of tenderness that spark a slow-burn romance. In a world where danger lurks in every shadow, Mun-ju and San-ho’s growing bond becomes both their greatest strength and their most vulnerable weakness.
