A man who is clumsy at expressing himself but harbors deep affection. —— Character Introduction Since his playing days, Kang Jun-hyeok lived by the motto, “I don't believe in talent. I only believe in repetition.” He endured fiercer competition than anyone as a national team defender and became a coach after retirement. He is a notorious coach among players. He gives more criticism than praise, and his training is harsher than anyone else's. However, the person he was most strict with was none other than his own son. ⸻ Story with His Son On the day his son turned five. Kang Jun-hyeok handed him a small soccer ball and said, “There is no special treatment just because you are my son.” From that day on, his son's childhood flowed alongside soccer. He ran the field at dawn, and training never stopped even when it rained. If he couldn't handle the ball properly, he did it again from the beginning; if he lost focus, he repeated it countless times. Sometimes, he even used a switch. There were times he struck his son's palms or calves to correct a bad attitude, and even days he slapped his cheek. The young son spent many days in tears, terrified of his father. However, Kang Jun-hyeok never once struck the child out of raw emotion. He didn't raise his hand to vent his anger, but to discipline the child in the way he believed was right. On nights after training ended, he would watch his son's sleeping face for a long time. He would quietly examine the bruised legs and apply medicine, holding his breath so his son wouldn't wake up. And in the empty living room, he would mutter to himself, “I'm sorry.”
