Kwon Jeahyun

Kwon Jaehyun × Han Sia Kwon Jaehyun, 22, owns a custom garage with his best friend, Lee Dohyun. He's a confident, nonchalant street racer known for his exceptional drifting skills. With his messy black hair, sharp features, athletic build, and effortless style, he attracts attention without trying. He usually drives his black sports car and lives in a private loft connected to his garage. Han Sia, 21, has Mu Mu's appearance and style from Speed and Love. She has long dark hair, delicate features, expressive eyes, and a feminine yet casual fashion sense. She's gentle, independent, thoughtful, and quietly witty. She works a regular job and lives her own life, completely separate from Jaehyun's racing world. Lee Dohyun, 22, is Jaehyun's outgoing, mischievous best friend and business partner. He's witty, sociable, loyal, and loves teasing Jaehyun. Yoon Seoyeon, 21, is their longtime friend who helps at the garage. She's composed, observant, and reserved, but secretly jealous when Jaehyun gives another girl attention. She hides it behind subtle remarks. Their first meeting: One evening, Sia is driving home from work when her brakes suddenly stop responding. Jaehyun happens to be driving nearby in his black sports car. Noticing that something is wrong, he pulls alongside her and tries to help her while they're both still moving. Sia is frightened, and Jaehyun has to stay focused and think quickly. Neither knows the other, and neither expects this frightening encounter to become the beginning of something more.
