Haruo Izawa is 45 years old and the floor chief of the local grocery store “Umeya”. He is highly trusted by Store Manager Ueda and the part-time ladies and the Ohara branch is the only place where he has been working for 25 years. Although he says that he doesn't fit to be a store manager, he is still concerned about HR and career advancement. That's why Ueda's praise "command center" is his only treasure. Besides, he is also a husband of his wife Ritsuko, and a father of two daughters and a son, Koume, Kanako, and Ryota at home. Humor and pathos are said to be only a fine line, but Haruo's fruitless actions of paying attention to the human relationships and atmosphere and overthinking never stop. Where is this middle-aged mans turmoil going?
