Episode 12 of "Our Movie" kicks off with Da-eum and Je-ha heading to the theater, eagerly anticipating the remake of "Love in White." However, their excitement wanes as only two other patrons join them, and the film proves to be a disappointment. Undeterred, Da-eum and Je-ha maintain their spirits, trading jokes and laughter amidst the boredom.
In the present moment, Je-ha and Da-eum resolve to cherish the scant joyful moments they share. Da-eum confesses her current happiness, inspiring them to conceptualize a fresh ending for their film. The conclusion remains ambiguous; Gyu-won lies dying in Hyun-sang's arms, yet her demise is never explicitly shown. Her final words, a heartfelt message of hope, leave AD Hong and Seung-won in tears. Jung-woo ponders whether Hyun-sang should weep, but Je-ha sternly directs him otherwise, believing that their unyielding love will empower Hyun-sang to carry on.
Elsewhere, Seo-yeong confides in Da-eum about her breakup with Jung-woo. Fearful of solitude, she inadvertently caused pain to those around her. Da-eum reassures her, emphasizing her inherent strength to overcome loneliness.
During the team dinner, AD Hong inadvertently finds herself taking care of Jun-byoung, prompting playful teasing from her colleagues. She deflects the attention by pointing out the growing closeness between Cheol-min and Ms. Jo.
Kim Hyun-chul opens up to Da-eum, revealing that his cancer has returned. Unsure of his next steps, he credits her with teaching him how to truly live. They vow to embrace each day with vigor and enthusiasm.
On the final day of filming, Dr. Lee finally visits the set, delighting Da-eum. Yet, she can't help but feel a pang of sadness as the project draws to a close. As she and Je-ha reflect on Gyu-won's story, it becomes evident that their conversation mirrors their own relationship. They conclude that as long as Hyun-sang harbors love for Gyu-won, her memory will endure forever.
The filming of the climactic final scene commences, marking the conclusion of the movie where Da-eum finds herself cradled in Jung-woo's embrace. However, both she and Je-ha mentally intertwine within the scene's fabric. As Da-eum's eyelids flutter shut, her mother's visage materializes before her. She trembles at the thought of letting go, yet her mother's soothing presence dispels her fears. Mrs. Lee reveals that she empathizes deeply with Da-eum and Dr. Lee's yearning for her, feeling their every sentiment. Da-eum's eyes snap open, signaling the wrap of an emotional milestone.
The journey into post-production begins, amidst which Je-ha, despite his bustling schedule, carves out moments for Da-eum. They embark on dates, indulging in cinematic escapades. Da-eum also bonds with Gyu-young, whose tears flow freely as they contemplate her future. Spring blossoms, and amidst the cherry blossoms, Da-eum and Je-ha gather petals, each one a testament to fleeting beauty. She silently wishes that his happiness with her is genuine, to which he reassuringly confirms. For Da-eum, this seems to be the twilight of her journey, and she yearns for Je-ha's heart not to ache in her absence.
Elsewhere, the rest of the cast and crew carry on with their lives. Cheol-min and Ms. Jo share a blossoming romance. AD Hong diligently hones her screenplay. Agent Go and Seo-yeong strategize for her next cinematic endeavor, while Gyu-young resumes her professional stride.
The remake of 'Love in White' hits theaters, revealing the opening scene as a figment of Je-ha's imagination. In stark contrast, Da-eum has transcended this mortal realm. The cinema halls are filled to capacity, heralding the film's triumph. Da-eum's name graces the writing credits, a poignant reminder of her legacy. Overwhelmed by emotions, Je-ha exits abruptly, his eyes welling up at the sight of her poster, a poignant farewell to the love that transcended life itself.
A year slips by, weaving a tale of friendship between Jae-in and Gyu-young, who now frequently gather at Jun-byoung's bustling restaurant. Mrs. Kwak, brimming with pride, extols the virtues of her daughters, Gyu-young and the beloved Da-eum. Meanwhile, Seung-won experiences a disconcerting sense of déjà vu as AD Hong casts a fresh face in the role of the female lead. Dr. Lee's movie nights have found a new companion in Je-ha, their bond deepening over cinematic wonders. Tragic news strikes as Kim Hyun-chul passes away, leaving a void in their circle.
The production of AD Hong's film is underway, mirroring the crew of the remake that once brought them all together. Jung-woo stars in the leading role, while Seo-yeong makes a graceful cameo as his amicably parted ex. Ms. Jo, ever the clandestine helper, slips Cheol-min some snacks, only for Je-ha to pilfer them during his visit, revealing his absence from their midst for a year. Seung-won checks in on him, to find Je-ha engrossed in penning his next screenplay. He returns to the comfort of his familial home, supported by AD Hong and Jun-byoung, whose blossoming romance becomes apparent.
Gyu-young sends a treasure trove of materials related to the remake—Da-eum's meticulously annotated script, evocative photographs, and her cherished camera. Included is a personal recording, intended solely for Je-ha's ears. In it, Da-eum vows that their paths will cross again, urging Je-ha to think of her whenever he feels her absence, for she claims she will sense it too.
As Je-ha embarks on filming his new movie, the male lead, played by a cameo from Kang Hoon, struggles to grasp his character's romantic inclinations. Je-ha, drawing inspiration from Da-eum's wisdom, elucidates that love often strikes without warning, a knowing that needs no explanation. The final frames of Our Movie Episode 12 capture Je-ha's newfound habit of recording his surroundings. He imagines Da-eum stepping into his reality, his longing for her palpable, and she, somewhere out there, presumably feeling it too.
