Kill It (2019)

In the heart of Seoul, a cold-blooded killer seeks redemption in the quiet life of a veterinarian. Kim Soo Hyun, a former assassin, conceals his deadly past from the world, his identity shrouded in mystery. He yearns for love, yet his past makes it difficult for him to forge sincere connections. Unbeknownst to him, an encounter awaits with Do Hyun Jin, a fiercely intelligent detective whose impeccable record at the police academy has earned her a reputation. Her exterior is as frosty as a winter in Seoul, but beneath it, she carries a wellspring of empathy. Hyun Jin's trust in her instincts and reliance on her surroundings shape her decisions, even as she grapples with her own traumatic past. As their worlds collide, will this assassin-turned-animal healer and the tenacious detective find common ground? In a city that never sleeps, two damaged souls are about to discover how love and crime intertwine in unexpected ways.
