- Tsubokura Haruko works in Sales at a mid-sized IT company Saotome Accounting Software. She loves the company and is good at her job, but at 35 years old she is concerned about what her future should hold.
Meanwhile, in an effort to increase profits, the company's president Saotome Ranko hires new graduate Ichijo Joe to create a startup within the company. Joe has excessively high self-esteem and presents himself as a business expert even though he is lacking in actual experience. Everything about him irritates Haruko, but to her dismay she is assigned to work with him to design a game and help safeguard the company's future.
