These are two chapters about Akemi temporarily going back to his uncle's restaurant to help out, and a third wheel making Yoruji feel insecure about it. It's not quite as wholesome as the main story as there's definitely more drama which began to feel tedious after awhile, especially when all of it could've been sorted out with a short text. As extra material, it's fine, and it portrays Yoruji's insecurity pretty well.
