Haruto Tateishi, a skilled prosecutor, is mistaken for a molester by Sakura Miyashita, a legal trainee, on the bus and has a terrible experience. After that, he happens to encounter Sakura, who is fighting with her boyfriend Sota Aoki (Hima Ikeda), who cheated on him, and ends up helping her without thinking... This leads to Haruto having to join Sakura in her drowning binge, and he ends up being pushed down by the drunken Sakura...!? A few days later, Haruto is reunited with Sakura, who has come to take his prosecutor training. Haruto is strict with Sakura, who is his bad fate, but for some reason, he can't leave her alone. The two started off with the worst possible encounter. Was this meeting a coincidence? Or was it fate?

Sakura is arrested on suspicion of murdering her ex-boyfriend Aoki Sota. Haruto is ordered by Sota's father, the Prosecutor General Aoki Soichiro, to ensure that he wins a guilty verdict, and is assigned to be the prosecutor in charge of the case. Sakura has no alibi, so he urges her to admit to the charges, but she refuses... and in fact, Sakura asks Haruto for his help. Meanwhile, Haruto's childhood friend and lawyer Umehara Ren is asked by Haruto to defend Sakura, a role that no one else wants to take. As Haruto continues his investigation, he discovers some evidence...

Sakura decides to tell Haruto how she feels, but he tells her, "Don't show your face in front of me again." Haruto then quits his job as a prosecutor, regretting that he couldn't become like his father, who was also a prosecutor... From then on, Sakura desperately spends her days searching for clues to the real culprit, relying on the whistling she heard on the day of Sota's murder. Two years later... Haruto works as a lawyer, and Sakura opens her own law firm, but is troubled by the lack of decent clients due to the past incident. Meanwhile, someone is watching Sakura from the shadows... Meanwhile, Sakura receives a request from a man named Hayashi Taku (Inoue Sora). And the defense for the defendant is, to her surprise, Haruto!

Sakura has decided to give up on her feelings for Haruto. On her way home, a "person who seems to be the real culprit" breaks into Sakura's office. Sakura loses sight of the real culprit, but Haruto rushes over and tells her that it's dangerous to stay there, so she decides to go to his house!? After that, Sakura's office's electricity and water are cut off, so she ends up staying at Haruto's house, but she can't stay there forever... Meanwhile, Haruto and Ren end up going out for drinks together. Sakura comes to the bar, saying that she is interviewing for a new agency.
