He used to cook only noodles for a while when he was a trainee but when he suffered a few deficiencies in his diet, he began cooking better meals.
Doing that led him to become a good enough cook. He was confident enough in his skills and the thought of having that fun with the boy rather than facing those relatives who did not care for his family when his mother was ill.
