Jonquil Peach, a top agent on the country's biggest secret agency 'SEG'. Jonquil is a workaholic, 24-year-old young woman who is promoted for her 5-year effort for 'SEG'. And after promotion, the good news was waiting for her. But who knew that the good news will turn her life upside down? The good news is the l vacation for Jonquil for her 5 years of hard work. But Jonquil is a work-obsessed woman who can't think anything but work.
When she comes back from work after 5 years. Her home looks like an unfamiliar place to her. Even she cannot remember her family member's faces clearly!
And once her elder sister Nancy influenced her to send an email to her idol, Mr.Jones, who is the top-secret spy of the country. No one has seen the face of Mr.Jones. Also he is known as the intelligent man of all time.
When Jonquil send her email to Mr.Jones, She receives a letter. Jonquil was confused about the letter but when she opened it a big surprise was waiting for her. She received an invitation to a grand party, which is throwing by Oliver Jones (a.k.a Mr.Jones), and in the letter, it is also mentioned that Jonquil can get a contract from Mr.Jones if he thinks she is much good for him.
Jonquil was super happy about it, and she decided to quit her new-part time job at the city bar. And she goes to work at the bar for the very last day as a bartender. When she was working, some perverts insult her. Jonquil thought that she will use her martial art skills in this case, but the employees of the bar aren't allowed to harm the customer. Also at that time a weird, mysterious man ordered a drink and he heard the insult words for Jonquil. Later on, he saved her from those men by kicking them once. And he was gone after the fight without taking the changes for the drink. Jonquil tried her best to find that man just to thank him, but she failed to find him.
Who had known that he was the T.S Spy-of the country?
