Unfortunate fate and murder bring the lives of Sakura and Haruto together.

Sakura is arrested on suspicion of murder, and Haruto is assigned as the prosecutor for the case.

Two years later, another turn of mysterious events brings Sakura and Haruto back together again.

Someone breaks into Sakura's law office, and Haruto insists she stay at his place for her safety.

When Haruto's ex-girlfriend Sakiko makes a sudden visit, Sakura pretends to be his new girlfriend.

Sakura refuses to give up on a client, seeing similarities with her own past.

Sakura confesses her feelings to Haruto in the spur of the moment.

Sakura (Saito Kyoko) is invited to dinner by Inaba (Ijima Sora), but she is troubled by her feelings for Haruto (Yagi Yusei). Meanwhile, Haruto becomes worried about Sakura who is heading to dinner with Inaba, and tries to secretly follow her to check on her, but is easily found out. Sakura asks him why he suspects Inaba, but he has no basis for his suspicion and is unable to answer. At that time, Haruto remembers Momoi Yuma (Asa Tatsumi), a forensic investigator who was attending Inaba's trial, and goes to see him. That night, Sakura receives a call from Momoi for some reason on her smartphone...

Haruto (Yagi Yusei) was afraid to start a relationship with Sakura (Saito Kyoko), but he couldn't stop thinking about her and ended up kissing her. But what was Sakura's reaction? Meanwhile, he learns that Momoi (Asa Tatsumi) has been found dead. Furthermore, a new body is found on the rooftop near where Sakura used to live. Curious, Sakura heads to the scene and by chance meets Inaba (Ijima Sora) and hears "a certain melody"...
