Currently with his one kid, Core usually works at a railroad building and constantly works there for the whole day till nighttime just to keep himself away from his son who wants to spend time with him. His girlfriend left him with their son because she only wanted him for his money which caused her to get into a car accident, dying instantly. Core is a loner, strict, airheaded, stubborn, and a guy who drinks. A certain event caused him to realize just how afraid he is of his own son and regrets it for not taking the time off for his only kid. He begins to change that as he is taking time off for him just to have quality time with his son. He even stopped drinking but still keeps the dadbod.
