Their three sons went missing. The case begins showing up in the media again and Ririn knows that it's eating at her father. One day, Ririn finds her father has been seriously hurt. Before he dies, he requests she keep his files about the case. However, her house was set on fire and the files are lost. She senses, after the fire, that someone is stalking her and she's attacked by someone unknown. Fortunately, a masked man saves her. She recognises him as Taiga, a rising designer who gave a scholarship to a student in her school. He suggests she move somewhere new. Later, Ririn is shot on her way back from a concert. Taiga is able to help her again, and he takes her to his house to recover. Ririn wakes up with the misunderstanding that he assaulted her. She attempts to escape and discovers a secret room in his house where many weapons are gathered. There, she finds her father's missing case files. She believes that Taiga is her father's murderer. Taiga must investigate the case and convince Ririn of his innocence.
