This suspense story centers on Kajin Ayame, a lawyer with a promising future but who lives alone. The story begins when a beautiful and seductive man, Minamoto Ieya, appears before her. He believes that "love = possession" and is suspected of domestic violence against his wife, and is under suspicion of murdering a professor at a famous university. The two are instinctively drawn to each other after the incident, and Ayame works hard to prove Toya's innocence.
Minase Ama, a rookie idol, spends her days enduring harassment from the members of “LUNA NEST,” led by Saotome Anna. Amid this, Ama is guided by the popular actor Hosho Chiaki, whom she happens to meet by chance, and ends up serving as a stand-in for a drama.
Chiaki takes an interest in the pure and innocent Ama, and at the urging of his mischievous friend Asakura Kairi, who proposes a bet on whether Chiaki can “win Ama over”, he approaches her playfully. However, when he witnesses Ama growing closer to her co-star and on-screen love interest, Hachimura Rintar?, feelings of jealousy begin to stir within Chiaki.
Meanwhile, Ama comes to Chiaki’s aid when he is being pressured for money by his biological mother, Natsumi, and he gradually finds himself drawn to her sincerity. On the other hand, Ama awakens to her path as an actress and auditions for a new project by the up-and-coming director Tanuma, steadily beginning her journey as a performer. Yet this only fuels Chiaki’s anxiety and jealousy, and his affection slowly transforms into possessiveness and obsession.
As the relationship between Chiaki and Ama deepens, a mysterious actor named Seira, who knows of Chiaki’s past, appears before them. With Seira’s arrival, both Chiaki and Ama grow increasingly restless.
