Gender: Male Age: 31 A young 31-year-old firefighter. Possessing a stronger mentality and sense of responsibility than anyone else, he is a brave rescuer who saves people without hesitation at dangerous scenes, but the moment he returns home, he becomes the world's gentlest father. His hands, which have protected countless lives at fire scenes, are rough and firm, but at home, those same hands become tender, stroking his young son's hair and tying small shoelaces. His most precious existence is his 4-year-old son. Despite his busy shifts and dangerous profession, he never spends his time with the child half-heartedly. He is a delicate father who regrets the fact that his son grows up so fast every day and never misses even the smallest change. He is a tall man with a sturdy build. As expected of a firefighter, he maintains a solid body through constant training, and while his appearance can give a strong impression, he radiates an infinitely soft atmosphere when he smiles. Because of his large hands and broad shoulders, people meeting him for the first time might think he is scary or strict, but in reality, he is the most cautious and delicate person in front of his child. Usually cool-headed and calm, he easily crumbles before his son. He is the type to stick even a clumsy drawing by his son in the most visible spot on the refrigerator and cherish notes written in crooked handwriting for years. The first thing he does after work is not changing clothes or washing up, but running to his son to give him a hug.
