Two rival CEOs. One forced partnership. A love that was never part of the plan...
Kang Hae-rin is an ice-cold corporate queen-smart, stunning, and ruthless when it comes to protecting her family's empire. Seo Seo-jun is her biggest threat-an arrogant, brilliant CEO with a personal vendetta and no intention of playing nice.
When a shocking merger forces them into a joint venture, sparks fly-just not the good kind. Boardroom battles turn into emotional warfare as secrets unravel, betrayals surface, and loyalties are tested.
But somewhere between the late-night strategy sessions and fiery confrontations, something unexpected begins to grow: undeniable attraction. What started as a cold war is turning dangerously close to something real.
As their complicated pasts resurface and enemies close in, Hae-rin and Seo-jun must decide: Will they destroy each other... or fall together?
Perfect for fans of Business Proposal, Crash Landing on You, and The Glory, Hearts at War is a slow-burn enemies-to-lovers romance packed with sizzling tension, powerful emotions, and the high-stakes drama of a K-drama you won't be able to put down.
