By passing the bar exam and becoming a lawyer at the age of 20, Shirase Masaru (played by Minami Hamabe) has solid legal knowledge, but due to his lack of worldly experience and stubbornness, he struggles in his job. One day, a senior lawyer at the firm takes on a case involving a suitcase... The client, Iriko Maki, has suffered sexual harm from the scion of a large construction company, but due to the influence of money and power, the truth is distorted, forcing her to stay silent. Unable to endure anymore, Iriko decides to hire a 'revenge agent' that she found online to take revenge. However, the revenge agent seems a bit off, and despite the payment, there are no signs of any actual revenge being carried out. Realizing it might be a scam, Masaru, armed with legal knowledge, seeks to lure the man into the open. The man he invites turns out to be the fraudster, Kuroiwa Kensuke (played by Masaki Okada). The justice-driven female protagonist, armed with her legal knowledge, teams up with the darkly cunning hero to take revenge on the esteemed scion targeting Iriko.
