Sugawara Yuga works in the sales department for the IT company Imuta Medical Data. At work, he is a cheerful person who performs his job well and gives advice to his junior colleagues. He declines requests for private meetings from female employees with a smile on his face. Yuga didn't join Imuta Medical Data for typical reasons. Before his older brother Sugawara Naoyuki died, Naoyuki developed a system at a company he founded. But, Imuta Medical Data announced a surprisingly similar system to the one announced by Naoyuki's company. Naoyuki was then found dead and his death was ruled a suicide. Yuga does not believe his brother committed suicide. He is also sure that Imuta Medical Data is somehow related to his brother's death. To reveal the truth of his older brother's death and to take revenge for him, he has infiltrated Imuta Medical Data as an employee.
One day, he happens to meet Imuta Hana, who is the daughter of the president of Imuta Medical Data. Yuga gradually approaches her to get the information that he wants, but he develops romantic feelings for her.
