An Observation Log of My Fiancée Who Calls Herself a Villainess Episode 3: An Observation Log of a Self-Proclaimed Villainess and Entering School.

The grand halls of Harum Academy welcome new students. Prince Cecil Alphas delivers a polished speech, every inch the charming royal. Watching him, Bertia Noches is a study in contrasts, her admiration for her fiancé battling with her mischievous determination to play her assigned villainess role. She sees a perfect prince, unaware he is already seeing through her act.

Inside the Student Council room, Charles Lionel and Baldo Norgins discuss Bertia's unexpected physique for a noble lady, noting her toned muscles. Cecil offers a soft, knowing smile, privately amused by their observations, which only confirms his own. His declaration that he will personally greet Bertia, departing immediately, shocks his friends. Charles marvels at Cecil's uncharacteristic emotional display, deciding to follow him out of sheer curiosity.

On his way to Bertia's tea party, Cecil spots Heronia Inderon in a pink dress, chasing a white bird with saccharine playfulness. While others might be charmed, Cecil's analytical gaze sees through the performance. He quietly instructs Culligan Dales Marden to investigate her, sensing a deliberate staging rather than genuine innocence. The prince trusts his instincts, and they tell him this girl is not what she seems.

Cecil finds Bertia hosting a tea party, where she is flustered by his unexpected arrival. She struggles to maintain her villainess persona, introducing her companions as "subordinates." Cecil is secretly impressed by her magical talent, noting her disguised spirit familiar, Kuro. He quickly deduces that Bertia's self-proclaimed "clique of villainesses" is actually an adoring fan club, led by Johanna Kelzwallen. The girls, Silica Lunia, Cynthia Sorelis, and Anne Cogarels, speak of Bertia's kindness, much to her visible frustration.

Cecil steps forward and presents Bertia with a pot of stunning blue roses, a gift for her enrollment. Bertia is stunned, recognizing them as a legendary item from her game memories, a detail that further amuses Cecil. He explains he cultivated them using his magic, specifically for her, to be as unique as she is. This tender confession completely disarms Bertia, leaving her blushing and speechless, her game logic overwhelmed by genuine emotion.

During a sunset walk, Bertia anxiously asks Cecil for his thoughts on Heronia, desperate for him to acknowledge the "heroine." Cecil bluntly dismisses Heronia as a "suspicious person," noting her forced laughter and staged bird interaction. This shatters Bertia's matchmaking plans, sending her into an internal panic about breaking the game's narrative. Cecil calmly debunks her "encounter event" theory, asserting his own judgment and preferring Bertia's honest nature over artificial charm.

Cecil meets privately with Johanna, adopting his full royal authority. Johanna reports on the Bertia Appreciation Club's success in protecting Bertia's reputation, showcasing her loyalty. Cecil then teases Johanna about her secret research into his younger brother, Shawn, exposing her crush and making her blush furiously. He entrusts Johanna with a "blacklist" of students, instructing her to monitor them, particularly Heronia Inderon, who he believes is the biggest threat to Bertia's peace.

Expecting Bertia's next scheme, Cecil finds Heronia dramatically "napping" in a rose garden, which he pointedly ignores. He quickly spots Bertia hiding nearby, orchestrating an "encounter event." When a caterpillar lands on Bertia, she screams and leaps from the bushes, tackling Cecil in pure panic, her elaborate plan forgotten. Later, Bertia lures Cecil to a classroom where Heronia waits, and the door is locked from outside. Cecil, bored with the contrived situation, simply kicks the door open, shattering both the lock and Bertia's matchmaking attempt.

A year passes. Bertia is visibly dejected over her complete failure to push Cecil and Heronia together. Cecil calmly explains the strict realities of noble social etiquette, clarifying why her "accidental encounters" were always doomed to fail. Bertia laments her inability to fulfill her villainess role or act as a helpful matchmaker. Cecil watches her, his expression tender, asking her to simply trust him and watch over him as his fiancée.

After Bertia departs, Cecil is left alone, contemplating his own emotions. He acknowledges a growing irritation at her persistent attempts to steer him towards another girl. He recognizes that he no longer desires any other maiden. His feelings have shifted; he only wants his unique, meddling, and truly wonderful fiancée, a realization that leaves him genuinely confused by the depth of his authentic emotions. He laughs at post-credit fan club reports, finding genuine warmth in the absurdity of life with Bertia.
