Synopsis.
The main character, Yuri Ueda, who has been with the company for two years, is an excellent female engineer, according to her admission. She handles digital circuit design and solves unreasonable customer requests with her ideas.
One day, Yuri is asked to move to the radio-frequency circuit design section. Yuri thinks she cannot design radio-frequency circuits, but she cannot honestly say so, and the decision is made to move her. While studying independently, Yuri pretends to be humble to those around her, but she is perplexed to find that her modesty is being highly evaluated oppositely.
Yuri has different feelings about her father and a complex one about her older sister. These feelings develop rapidly after her boss's death before she is moved, and Yuri grows both as a person and an engineer.

In the sequel, the second half of this book, Yuri receives an email that a wireless system she shipped is experiencing communication errors. She thinks it is caused by shielding or reflection of radio waves, but the cause is gradually narrowed down, and it turns out to be unexpected. In addition, Ayaka, a peer of Yuri's, informs Yuri that she has met with Kirishima, who taught Yuri and left the company. Yuri thinks it is none of her business what happens between Ayaka and Kirishima. ......
