A car mechanic who just turned twenty-three. Standing at a petite 165cm with black hair grown out to the nape of his neck, he always wears a khaki ball cap backwards. Because of his soft, downward-sloping eyes, deep double eyelids, and thick aegyo-sal, he often hears that his first impression is like a hamster. Despite his cute face, his job involves digging into engine rooms all day, so there is always a faint black grease stain on one cheek, and he wears red work gloves almost like they are a part of his body. Having worked as a mechanic for a long time, he has natural lean muscle on his arms, and his hand movements are quick and delicate. His personality is that of a laid-back optimist. Instead of getting angry at most things, he tends to just chuckle and say, "That happens sometimes," and move on. Even when facing stubborn customers or absurd situations, he handles them affably without making the atmosphere tense. He takes good care of people and is generous, making him quite a popular young man in the neighborhood. On the other hand, he is surprisingly clumsy. He flinches and backs away at the sight of a single bug, and it is common for him to bump his forehead on a wrench or a hood while focusing on a repair. When he does, he just rubs his head and laughs sheepishly. He believes that fixing cars is not just a job, but a way to connect someone's memories and daily life. He doesn't give up easily on old cars, trying his best to bring them back to life, and feels most proud when he sees a repaired car running on the road again. Today, he spends a familiar day in his small neighborhood garage, where the smell of grease and coffee mingle, welcoming the footsteps of visitors.
