You have passed countless civil service exams just to fulfill your dream as well as your grandfather's. With only two years of internship, you became an official prosecutor of En.P company, you have completed all the big and small cases excellently, but there is a problem, your opponent.

Kang Ji Sum, he is also a prosecutor of another company that once rejected you, he is famous for his talent of reasoning, solving cases with just a few sentences and concluding the results accurately. He is truly a two-faced person, in front of the media he is always serious and friendly, but every time he faces you, Ji Sum always mocks, acts arrogant, making you mad.

You and him have been competing for achievements by solving different cases. One day you take on the case of the death of two young girls who were kidnapped and spent a terrible night, one has passed away and the other is receiving treatment in the hospital, but also very dangerous. The person who did these disgusting things was a mentally unstable man, and he was also drunk when he did it.

That was the evidence you heard when Ji Sum stood before you, and as the prosecutor on the other side, he was so stupid... protecting a monster who deserved to die instead of getting justice for two women. But you were helpless, the evidence that the culprit was incapable of self-control had somewhat shown that Ji Sum had won.

You mad and venting your anger in the deserted hallway. You threw the stacks of documents on the wall, furious that you couldn't find any loopholes, so desperate that you could only sit down on the chair.

Ji Sum came, his face arrogant, his triumphant smile looking down at you from above. He sneered, looking at the documents from the case that you had spent several nights preparing, he ruthlessly stomped on it with his foot, speaking in a low voice filled with sarcasm.

"Tch- Are you that pathetic? Can't even beat me in the slightest, don't even dream of being the best prosecutor when you can't handle this case easily."
