When a young employee transfers to a new department, she braces herself to work under a manager rumored to be a terrifying brute. However, she quickly discovers that the intimidating department head, Nishijima, is not a demanding black company boss but rather a white knight of work-life balance who is completely committed to raising his child. The manga follows Nishijima, a man with a fearsome face but a fundamentally gentle personality, as he navigates the daily chaos of corporate life while being a dedicated father. The comedy arises from the juxtaposition of his tough appearance with his parenting duties, such as accidentally answering a client’s phone call by saying, Hello, it’s Papa, or having to leave an important meeting because of an urgent summons from the daycare center. His subordinates, including the new transfer named Yukari, watch in awe as their boss models a revolutionary style of leadership where leaving on time every day is the norm and taking time off for a child’s sick day is not just accepted but actively encouraged. The story celebrates these company and childcare moments that anyone can relate to, portraying a fun Let’s work style reform where taking a call from the nursery takes priority over an executive board meeting and a wet wipe is a universal tool for any mess.
