Episode 10 of "Our Movie" kicks off with Je-ha once more immersing himself in a reimagined scene from the remake, where Seo-yeong assertively declares that he should pick her, insisting she will unwaveringly stand by his side. The scene then transitions to a solitary Je-ha, presumably grappling with the aftermath of Da-eum's demise.
Presently, Da-eum delivers a heartfelt monologue, elucidating the profound significance of the film to her. As snowflakes gently descend, signaling the end of the day's shooting, conversations buzz around the set, filled with speculation and gossip sparked by her revelation.
Agent Go, convinced that the movie is destined for greatness, attempts to persuade Seo-yeong to depart but she steadfastly refuses. Meanwhile, Dr. Kim confides in Je-ha, revealing that Da-eum's condition has deteriorated, a fact she has been diligently concealing.
Cheol-min's circle of friends find themselves anxious, contemplating their uncertain future should Da-eum's health take a turn for the worse mid-production. Assistant Director Hong stumbles upon Jun-byoung, tears streaming down his face, overwhelmed with guilt as he feels he has let Da-eum down as her manager.
By the next morning, the location is blanketed in snow, prompting Je-ha to announce an unplanned break. Da-eum berates herself, but he reassuringly vows that they will see the film through to completion, come what may.
Investor Han, intent on supplanting Je-ha, arrives with Director Park in tow. Meanwhile, some unscrupulous members of the crew have already disclosed Da-eum's illness to the internet, casting Je-ha under a storm of criticism for exploiting her condition. Han brandishes the threat of withdrawing funding, yet even Seung-won wavers at the prospect of bringing the sleazy Park on board.
Reporter Noh lurks around, voraciously seeking more gossip, and steadfastly refuses to exclude Seo-yeong's name from his articles. Agent Go, incensed, snaps Noh's camera in two. Cheol-min, fed up, resigns in protest, refusing to compromise Da-eum's well-being or his colleagues' integrity for the sake of a movie.
As the cast and crew depart the location, a exodus ensues, with most of them abandoning ship. Je-ha and Seung-won share a drink, the latter feeling sympathy but failing to grasp Je-ha's underlying intentions. Je-ha confides in Seung-won that all of Du-young's films were penned by Eun-ae, his mother, and he aims to uncover this truth. Seung-won is distressed, foreseeing ruin for Je-ha.
Back in the bustling city, Jae-in is consumed by regret over her harsh words to Da-eum. Director Park seeks Agent Go's assistance to oust Je-ha from the project. Cheol-min silences his latest director's disparaging remarks about Da-eum but ignores Je-ha's calls. Only AD Hong, Jun-byoung, and Gyu-young remain, gathering in Da-eum's hospital room for solace.
Desperate, Je-ha attempts to secure a loan to complete the film. He visits Da-eum, and they share heartfelt conversations about how they have mutually empowered each other. Meanwhile, at a nearby diner, Gyu-young, Hong, and Jun-byoung share a meal. Hong reveals she is writing a screenplay, which captivates Jun-byoung, who can't help but flirt with her, prompting an embarrassed Gyu-young to hastily excuse himself.
Je-ha and Da-eum find themselves engrossed in a film directed by Du-young, only to stumble upon a tearful Jin-yeo in the cinema. Jin-yeo's poignant tale finally unfolds through Je-ha's revelations to Da-eum, interspersed with poignant flashbacks.
In these flashbacks, Jin-yeo and Eun-ae are portrayed as inseparable friends. Jin-yeo, aware of Du-young's plagiarism of his screenplays, urges Eun-ae to claim credit for 'Love in White'. However, Du-young stubbornly refuses, prompting Jin-yeo to issue an ultimatum—expose him or face ruin. In retaliation, Du-young's wife fabricates rumors of an affair between Jin-yeo and Eun-ae, leaving Jin-yeo disillusioned and reluctant to collaborate with Du-young ever again. Yet, Eun-ae, desperate for Jin-yeo's participation in 'Love in White', pleads with her, imploring her to reveal the truth to Je-ha when the moment arises.
Returning to the present, Je-ha confides in Da-eum, revealing his newlyfound understanding of Eun-ae's masterpiece, 'Love in White'. Their conversation drifts to nostalgic recollections of their first encounters, filled with lighthearted banter and heartfelt gratitude for the changes they've inspired in each other.
Later, at lunch, Da-eum shares a meal with Seo-yeong, while Je-ha embarks on a mission across town, pledging his commitment to the film's crew, reassuring Cheol-min of his accountability. Meanwhile, Seung-won grapples with the challenge of reassuring investors. Je-ha steps in, urging him to enlist Reporter Noh's help, much to the producer's reluctant agreement.
Upon his return to the hospital, Je-ha finds Da-eum in the throes of a seizure. Dr. Lee questions whether Je-ha's departure is the right choice for Da-eum. Their dialogue delves into the complexities of loving someone destined to leave us. Je-ha, baring his soul, vows never to forget his mother or Da-eum. Moved by his sincerity, Dr. Lee implores him to complete the film for Da-eum's sake, seeing it as the ultimate fulfillment of her dreams.
As Our Movie Episode 10 draws to a close, a sorrowful Dr. Lee discharges Da-eum, and Je-ha escorts her to his family home. Reunited with a majority of the crew, including Cheol-min, Da-eum is overwhelmed with emotion. She bursts into tears and confides in Je-ha, admitting she's not prepared to die. Je-ha, tears streaming down his face, embraces her tightly. The scene fades to the iconic tree that has served as the backdrop of their journey since the series' inception.
