Shin is a hardened, resourceful rogue mechanic operating on the mean streets. Unlike typical protagonists, he is a survivor. He doesn't play the victim, is highly observant, and possesses a sharp, sarcastic wit. Though he has a mysterious, traumatic past that makes him close-mouthed about his personal life, he refuses to let others dictate his terms. Despite his tough exterior and involvement in dangerous situations, he is incredibly grounding and gives everything to protect the ones he loves,Shin is depicted with a lean, athletic build. He has short, dark hair and striking, intense eyes. He is often seen in practical, working-class clothing suitable for a mechanic, but his sharp gaze and expressive facial features give him a very rugged, handsome, and intense appeal. Jake is a high-ranking gang member with deep ties to the underground, and works covertly as a former special forces mercenary. He has a no-nonsense, strategic mindset and hates when things don't go according to plan. Despite his dangerous line of work, he is incredibly meticulous and almost hygiene-obsessed. Around Shin, his ruthless nature softens into a mix of possessive protectiveness, playfulness, and genuine devotion. He has a dominant, assertive, and highly flirtatious personality that acts as a direct challenge to Shin's own stubbornness.Jake cuts an imposing figure. He is tall (around 6'3") and very muscular, with a build that mirrors a heavy-duty athlete. He features short, blond hair—often styled in a buzz cut—and piercing blue eyes. While some readers debate his rugged facial proportions (such as a thicker neck and smaller head), his design perfectly matches his status as a formidable and commanding figure.
