The courtroom is packed to capacity -- lawyer Ayame Hanajin (Kumiko Aso) sits in the defendant's seat. "What was that crime...?" she mutters to herself as if asking herself... And then -- the trial of a "murder case" begins -- time rewinds to one year ago -- Ayame works hard every day as an excellent, solitary lawyer. One day, she is invited as a panelist to a domestic violence victim seminar held by a women's group where charismatic businessman Yoko Mogami (Misuzu Kanno) serves as a director, and there she meets a woman. The pretty woman, who calls herself Natsune Minamoto (Kana Kita), works as a manicurist at the salon run by Yoko, and her husband and Yoko's son Jun (Motoki Ochiai) were classmates in high school, so she and her husband are living in a detached room in Yoko's house. Furthermore, even though she hints at the fact that her husband is abusing her out of love, she smiles meaningfully and leaves the scene.

The courtroom is completely filled to capacity -- lawyer Ayame Kajin (Kumiko Aso) sits in the defendant's seat. "What was that crime... for?" she mutters, as if asking herself... "I will defend you." Lawyer Ayame Kajin (Kumiko Aso) listens to the plea of ​​Natsune Minamoto (Kana Kita) who is crying, "Help my husband!" and visits the detention center to see her husband, Toya Minamoto (Akihisa Shiono). Toya is suspected of being the "murderer" in the mysterious death of Ayame's mentor, university professor Okutaro Nada (Shiro Sano). Nada's wife Yoko Mogami (Misuzu Kanno) testifies that she saw Toya leaving the scene last night when the incident occurred.

On the night of Nada Okutaro's (Sano Shiro) funeral, Hanajin Ayame (Asou Kumiko) is unable to contain her passion and crosses the forbidden line with Minamoto Toya (Shiono Akihisa). Unable to forget Toya, she visits the fencing club where he works, under the pretext of returning the T-shirt she borrowed that day. However, when Ayame tells him that it was a one-night mistake, Toya only looks at her with a lonely look in his eyes... Ayame leaves, wishing he would stay, and this was supposed to be the end of their relationship. However, that night, Toya calls her in a painful voice, saying, "I don't think I can act like nothing happened," and Ayame is made to realize that she feels the same way. The two of them become even more immersed in their forbidden love..

A sudden act of violence from a man she was supposed to love. After being beaten by an enraged Minamoto Toya (Shiono Akihisa), her house was ransacked, and Ayame Hanajin (Asou Kumiko) was left alone in her room, stunned. "What just happened was a dream," she wanted to think, but the pain on her cheek and body wouldn't allow it... The next day, she hid her wounds with makeup, finished work bravely, and returned home to find Toya holding a flower in front of her apartment building... Ayame's heart was shaken when Toya apologized to her with tears in his eyes, saying, "I didn't mean to do that." However, when she refused, saying, "We're over," in an attempt to break off their relationship, since that night Toya began to deliver a flower to Ayame's mailbox to convey his feelings. With each passing day, Ayame finds herself struggling with her own feelings of wanting to forgive her brave boyfriend...

Minamoto Kanon (Kita Kana), who broke into the law firm where Hanajin Ayame (Asou Kumiko) works and caused a suicide commotion, suddenly disappeared immediately afterwards. "Let's stay together." Ayame, who had lost everything, took the hand of the distraught Toya (Shiono Akihisa) and invited him into her home... and the two began living together. Life with Toya was a happy one for Ayame. Since Natsune caused the commotion, Ayame had been treated coldly at the office and had lost everything. However, it wasn't painful when she thought that Toya was waiting for her at home... and gradually Ayame began to break down as a person.
