Milly Asteara, a noblewoman known for her icy demeanor and titled the final boss, is murdered by Angelina Grey, a self-proclaimed villainess who believes the world is an otome game. Milly then awakens three years in the past with all her memories intact, determined to escape her humiliating fate by rewriting the future. Rather than seeking revenge, she decides the key to survival is to build genuine connections, choosing allies and reevaluating the world around her at the royal academy. Her rival, Angelina, remains fixated on securing her happy ending with Prince Gilbert and is willing to kill to get it, turning everyday academic life into a battlefield of poisoned teacups and political schemes. For Milly, this second chance is not just about avoiding death but about carving out a place where she can truly belong.

The story follows Milly Asteara, an intelligent and powerful magic user who is socially awkward and struggles to connect with others, despite her noble background. Her antagonist is Angelina Grey, an isekai’d individual who believes she is the protagonist of an otome game and views Milly as an obstacle. Other key characters include Prince Gilbert, the object of Angelina’s obsession, and Sierra, the game’s designated heroine. The student council includes figures such as Nicholas, the president; Edgar, the vice president; and Lucius, alongside the suspicious Ike, who harbors a grudge against Milly’s family. Milly’s father, Kyle, is widely regarded as a terrible person on the verge of treason, but he is later revealed to be overprotective and socially awkward, much like his daughter.

The setting is a noble academy where political rivalries and social hierarchies create a dangerous environment for anyone without allies. The first volume focuses on Milly’s attempts to avoid assassination by befriending outcasts and navigating a plot involving poisoned teacups at a tea party. She also confronts Angelina directly, using magic to force a confession and establish herself as a threat. The second volume introduces a new complication: someone else remembers the original timeline and believes the country is heading toward ruin, with Milly inadvertently helping that outcome. Milly must also contend with her father’s terrible reputation, which isolates her socially, and prepare for final exams while dealing with a student council member who remains hostile toward her. Despite her growing circle of friends, including girls she saved from Angelina’s schemes, Milly remains awkward and struggles to read social cues, leading to misunderstandings and escalating tensions.
