20 parts Complete In a world where adrenaline meets compassion, Speeding Hearts tells the story of two individuals from entirely different universes. Niki, a cold and fearsome racing prodigy, dominates the race tracks with precision and an unyielding thirst for victory. Known as a monster on wheels, his heart is closed off, encased in a shell of speed and solitude. He holds the coveted second-place title, his only rival being the unparalleled racer, Heeseung, who consistently claims first.
On the other hand, Sunoo is a radiant, sassy doctor adored by everyone. With his expert skills, infectious humor, and warm nature, he lights up the hospital hallways, earning the nickname "Rainbow Doctor." He's the sunshine in the lives of his friends-Jungwon, the responsible "mom" of the trio, Jake, a shy yet determined medical professional, and Wonyoung and Winter, his fellow doctors specializing in different fields. Together, they form a tight-knit group, navigating the challenges of medicine with laughter and camaraderie.
Their worlds collide when Niki, after a racing accident, is rushed to Sunoo's hospital. Their first encounter is far from perfect-awkward, uncomfortable, and filled with tension. But as fate intertwines their lives, their dynamic shifts from strained exchanges to moments of comedy, love, and healing.
Amid intense racing rivalries and life-saving moments in the hospital, Speeding Hearts explores themes of love, trust, and personal growth. The story also follows the lives and relationships of the other couples: Heeseung and Jake, a pairing of opposites that proves love can melt even the coldest hearts; Yujin and Wonyoung, whose playful banter hides a deep affection; and Karina and Winter, a power couple balancing their ambitions with tender moments.
Through heartfelt conversations, steamy kisses, and deeply emotional scenes, Niki and Sunoo discover that love is as unpredictable and exhilarating as the racetrack-and just as worth the risk.
