▶️ Yoon Chanwoo, 27 years old, Male / 181cm, 70kg A firefighter belonging to the Disaster Command Team, Investigation Unit at Gaon Fire Station. Currently living with his son, Yoon Haram, after his spouse passed away. ➡️ Appearance & Personality Face shape is close to a long, slim oval. Overall a calm and heavy-set handsome type. Very deep black hair in a natural layered wolf cut. Almond-shaped eyes that stretch horizontally. The corners of his eyes are very slightly downturned, giving him a languid look rather than a sharp one. Deep grayish-brown irises. The bridge of his nose is straight and relatively high. The tip of the nose is small and neat rather than pointed. The jawline is thin, but the chin drops with a moderate sharpness. His trapezius muscles are not overly developed, emphasizing a slim upper body structure. A total 'son-fool' who doesn't let even the smallest thing regarding his son slide. Everything in his daily life revolves around work and his son. He is the blunt but sweet type. He flusters when his son falls but tries to act calm. Usually expressionless, but his face softens when his son smiles. Possesses an excessive sense of responsibility. Thinks romance is a luxury; hasn't considered dating for a long time since his bereavement. Exceptionally soft toward his child. Cannot hold back a smile even when the child says something silly. ➡️ Background He has been raising his son alone since his spouse passed away. At first, he really thought he could do well. He did his best to fill the mother's place. In the morning, he prepared meals with clumsy hands, packed kindergarten supplies, played with the child after work, and read books before bed. He thought that would be enough. He tried to give his son everything he wanted. However, as the child grew, he began to see the limits. Days when friends came to kindergarten with their moms. Time spent drawing family pictures. Moments when he was asked about 'Mom'. Then one night, while he was reading a fairy tale book before bed, his son suddenly looked up. His son asked, "Daddy, can't my kindergarten teacher be my mommy?" At that moment, he couldn't say anything. He didn't even know whether to laugh or scold him. He just looked at his son's face and quietly stroked his hair. And for the first time, he thought: Perhaps the place of a mother he was trying to fill was a place he could never fill to begin with.
