Season 1

While undergoing cancer treatment, Misa discovers her husband Tomoya is having an affair with her best friend Reina, only to be murdered by the two of them. Instead of dying, she somehow wakes up in 2015, ten years in the past. Armed with knowledge of what’s to come, Misa sets out to rewrite her fate and plans her revenge.

Wataru, who has always been an passive observer of his first love Misa, finds his heart racing when she suddenly reappears in his life. Misa learns that her second chance isn’t without consequences. Misa makes her first move to rewrite her dreaded memories from her past life, at her class reunion.

After breaking up with her boyfriend, Reina begins pursuing Wataru. With her plan to play cupid for Tomoya and Reina falling apart, Misa kicksoff the “Tomoya Makeover Project.” Meanwhile, Misa overhears Wataru and Miku having a friendly chat, and starts to question their relationship as she heads off to a vineyard on a business trip.

Misa accuses Reina and Wataru's relationship, but quickly finds out Reina made a move to provoke Misa. Misa stages her happy relationship with Tomoya to make Reina jealous, but the plan takes a dark turn when Tomoya once again shows signs of violence.

Misa learns that she and Wataru shares a connection dating back to their university days. With that realization, she gradually begins to open up and grow closer to him. Meanwhile, frustrated that Misa isn’t falling apart as planned, Reina becomes increasingly restless and finally makes a move to seduce Tomoya.

Misa teams up with Wataru to save Miku from being falsely accused as she was in her first life. Meanwhile, Misa has a complete makeover and causes a scene during her formal meeting with Tomoya's parents. As Misa storms off, Reina arrives right on cue.

Reina claims that she's pregnant to take Tomoya from Misa. Reina now struggles with mounting tension from her mother-in-law. Meanwhile, with the pressure off, Misa begins enjoying her life of freedom with Wataru. As emotions stir on all sides, Reina and Tomoya's wedding day finally arrives.

After learning that everything was part of Misa’s calculated plan, Reina and Tomoya confront her in rage. Meanwhile, just as Misa believes everything is finally over, she learns that the cancer from her first life may have passed on to someone else.

Wataru suddenly vanishes without a trace. As Misa searches for him, she uncovers a shocking secret about his past. Meanwhile, Reina, feeling betrayed by everyone around her, begins to spiral out of control, and gets dangerously close to Tomoya’s mother and Misa’s grandmother.

Determined to put an end to her long-standing feud with Reina, Misa makes her final decision. Wataru also makes up his mind to protect Misa in his own way. But just then, an unexpected call from the police delivers a shocking revelation that leads them straight into a dangerous trap.
