Even a Replica Can Fall in Love Episode 1: A Replica Never Dreams

A gentle voiceover introduces Nao, a replica, a girl who serves a purpose rather than living her own life. We see her stir on the floor, while Sunao Aikawa, the original, sleeps deeply in her bed, oblivious to the world. Sunao wakes, groggy and indifferent, instructing Nao to attend school in her stead, too tired for the day. Nao accepts this role with a quiet grace, her energetic demeanor a stark contrast to Sunao's persistent lethargy.

Nao moves through Sunao's home with quiet purpose, preparing breakfast that she herself will not eat, drinking only water. Her meticulous routine extends to grooming, ensuring Sunao's public appearance is flawless. Cycling to school, she pauses on a bridge overlooking Mount Fuji, reflecting on sixteen summers spent in this role, her directives clear: to study, exercise, and ensure Sunao's anonymity. Inside the school, the stifling heat of a broken air conditioner adds a mundane discomfort to Nao's already demanding schedule, as she faces classroom duties with quiet resolve.

After a lesson, Nao diligently erases the chalkboard, lost in her task, when a tall boy approaches. It is Syuya Sanada, a former basketball star, who silently helps her with the other side of the board. His presence is unexpected, catching Nao off guard. Their brief exchange is hesitant, with Sanada dismissing his past fame and suggesting Nao drop the formalities. This quiet interaction is their first, hinting at a subtle shift in Nao's routine.

Nao finds solace in the Literature Club room, greeted by Ritsuko Hironaka, affectionately known as 'Ric-chan.' Their friendship, formed under the guise of Sunao, is genuine and deep. A flashback reveals Sunao and Ritsuko were childhood friends whose bond fractured after a fight and a move, only to be rekindled by Nao in high school. Back in the present, Nao offers Ritsuko thoughtful, honest critique on her manuscript, digging for the raw emotions. Ritsuko is visibly moved by Nao's insight, her passion reignited, cementing their mutual respect.

A pivotal flashback takes us to Sunao's childhood, where, distraught after a fight with Ritsuko, the seven-year-old Sunao wished for someone to apologize in her place. Suddenly, Nao materialized from a shimmering void, an identical twin willing to fulfill the wish. This act of creation began their secret partnership. Through narrated experiments, the rules of Nao's existence are laid bare: she manifests only when called, disappears with a 'Goodbye,' and leaves behind any objects she acquires, a strange consequence of mass conservation.

A montage illustrates the deepening dependence of Sunao on Nao over the years. What started as minor errands evolved into Nao living almost Sunao's entire public life. Sunao retreated further into her room, using Nao to avoid any perceived anxiety or stress. Nao, in turn, harbors a silent longing to be genuinely helpful to her creator, even as she observes Sunao drifting away from reality. The montage ends with Nao alone in a school hallway, a stark image highlighting her growing sense of self.

The oppressive heat in the Literature Club room becomes unbearable as the old electric fan sputters and dies completely. Ritsuko is devastated, knowing the club lacks the funds for a replacement. Nao feels a pang of guilt, acutely aware that she has no money of her own, as Sunao controls their allowance. She recalls a time when she earned 'help money' as a child, but those resources are now inaccessible to her. This small crisis underscores the practical limitations of Nao's existence and the power dynamic with Sunao.

The club room door opens abruptly, and Syuya Sanada enters, startling Nao once more. He calmly announces his desire to join the Literature Club, shocking both girls. Ritsuko is thrilled, quickly moving past her surprise to welcome the famous former athlete. Nao, however, stands frozen, her mind racing to process the implications of this unexpected development on her meticulously managed school life. Ritsuko then pulls Nao along to get the club application form, rushing to finalize his membership, leaving Nao in a whirl of confusion and strange excitement.

While at the faculty office, Sanada encounters his former basketball coach, leading to an awkward exchange. The coach expresses concern about Sanada's new path, but Sanada shuts him down with a cold, dismissive attitude. Nao observes this from a distance, noticing a fleeting look of pain on Sanada's face that he quickly conceals. She realizes his decision to join the Literature Club is likely a conscious effort to distance himself from his past and the injury that ended his athletic career.

Nao and Sanada find themselves in the school library, searching for reading material. Their conversation unexpectedly deepens as they discuss Natsume Soseki's 'Kokoro.' Sanada admits he only remembers a specific, cynical quote, yet his honesty impresses Nao. She offers to lend him her copy of the book for further discussion. Standing among the quiet rows of books, Nao discovers Sanada is far more thoughtful and sincere than his 'cool guy' reputation suggests, marking the true beginning of their connection.

The scene shifts abruptly to the classroom, where the original Sunao sits bored and disconnected. Sanada approaches her, assuming she is the girl he just spoke with in the library, attempting to discuss the broken fan. Sunao has no knowledge of this conversation and reacts with confusion and irritation at being disturbed. This moment is rich with dramatic irony, as the audience understands the deception while Sanada remains completely unaware, highlighting the inherent danger of Nao and Sunao's secret arrangement.

Back in the Literature Club room, Sanada arrives, carrying a large box containing an old but functional electric fan from his house. Ritsuko is overjoyed, practically hailing him as a hero for saving them from the heat. Nao is touched by his thoughtfulness, observing the budding camaraderie as they set up the fan. For the first time in the episode, the club room feels cool and comfortable, a tangible symbol of Sanada's integration. The trio then holds a mock 'memorial service' for the broken fan, a quirky idea from Nao, creating a shared moment of silliness and genuine warmth. Ritsuko officially welcomes Sanada, and the three settle into a peaceful afternoon of reading and quiet conversation, leaving Nao to reflect on the unexpected complexities and meanings now entering her life as a replica.

In a post-credits scene, the classroom tension from earlier is revisited and intensified. Sanada approaches Sunao again, his tone more insistent, seeking clarity about the fan incident he believes they discussed. Sunao's reaction is even more hostile and bewildered than before; she has no memory of the conversation and perceives his persistence as a bizarre joke. Sanada's expression shifts from confusion to a deep, unsettling suspicion that something is profoundly wrong with the girl in front of him. The episode ends on this high-stakes cliffhanger, directly setting up the central conflict for the next installment.
