Her Love Boils Bathwater

Futaba Kono, Rie Miyazawa, a single mother, has spent years raising her teenage daughter Azumi Kono, Hana Sugisaki, who has long faced the pains of being unpopular and bullied at school. When Futaba unexpectedly collapses at work and is rushed to the hospital, doctors deliver a crushing verdict: she has terminal cancer and only a few months left. Faced with a countdown she cannot change, Futaba makes a quiet but unwavering choice—to use her remaining time to reshape her family’s life for the better, to leave behind a sense of safety, warmth, and connection that survives her.

In a bid to restore the family’s stability, Futaba hires a private investigator, Tarō Suruga, to locate her husband, Kazuhiro Kono, Joe Odagiri, who had walked away years earlier for another relationship. The past romance wobbles under the weight of new truths: the other woman left him, and he has since been left to raise a 9-year-old daughter, Ayuko, Aoi Ito, on his own. With a practical plan in mind, Futaba hopes to bring Kazuhiro back into the fold so they can rebuild a home that supports all three generations—and the two girls—instead of fragments of a family splitting at the seams.

Kazuhiro agrees to return and live with them, but the reunion is awkward and imperfect. Azumi, still carrying the hurt of being left behind, is wary of the man who once abandoned them. Yet the family grinds forward, discovering a path to a more secure life through the communal labor and comfort of the bathhouse they reopen together. The revival of this small business becomes a symbol of resilience for everyone, a shared project that can steady them as Futaba’s illness casts a shadow over everything they do.

Meanwhile, Azumi’s life at school proves to be another kind of test. During gym class, her uniform is stolen, and the public humiliation jolts her into a moment of crisis. She initially refuses to return the next day, but Futaba steps in with quiet authority, urging her to stand up for herself. Azumi heads back in her gym clothes, endures the taunts, and, in a rare burst of boldness, demands the return of her uniform. The episode is tense and painful, and even as she vomits from nerves, she finds a way to reclaim dignity in a moment of schoolyard exposure. Ayuko, whose own history with abandonment colors her choices, runs away from home to seek out her mother on her birthday. Futaba, reading the signs of her child’s distress, deduces where Ayuko might be and, with Azumi in tow, sets out to bring her back. The family completes the birthday with a simple, intimate shabu shabu meal, a small ritual that underscores their fragile but genuine unity.

As the family’s bonds strengthen, they set out on a road trip for a vacation that feels like a chance to breathe. On the road they meet Takumi Mukai, Tori Matsuzaka, a young man hitchhiking from Hokkaido who claims to be fleeing from a wealthy but coldly distant family. Futaba, initially skeptical and blunt, challenges him about the value of time and the ways people waste their chances in life. He admits he is running from his own constraints, and in a moment of honesty he asks for help, proposing that perhaps he could at least see Hokkaido. Futaba’s impetuous, no-nonsense approach gives way to a grudging sense of responsibility, and she asserts that he should go to Hokkaido to see the world he’s missing. He asks to meet them again, and she agrees, leaving the door open for a tenuous, hopeful future.

The journey brings them to a coastal town near Mount Fuji, where they savor spider crab and the sea’s bracing air. In a restaurant overlooking the water, they encounter a deaf woman who turns out to be Azumi’s biological mother, Kimie Sakamaki, Yukiko Shinohara. Kimie’s presence adds a new layer to Azumi’s sense of belonging and lineage, and Azumi, who has learned sign language at Futaba’s insistence, communicates with her birth mother in a moment that blends surprise with a fragile, aching clarity. Futaba’s careful preparation for these reunions—knowing that the truth might be difficult to bear—pays off as the two women connect through a shared language of need and memory.

Later, Futaba and Azumi pick up Ayuko from her detour and return to the family’s circle. Futaba collapses once more and is rushed to the hospital, where the private investigator reappears with news that he has finally tracked down Futaba’s own mother. At her request, he takes Futaba to see this elder figure in Tokyo, hoping to fill a long-standing void. The moment of confrontation proves both hopeful and heartbreaking: the elder mother denies the earlier story, and Futaba, standing in a house full of people who might be kin, feels a surge of conflicting emotions. Inside, Futaba glimpses the possibility of a larger family, yet the scene also reveals hard truths about the past. Overwhelmed, she shatters a window in the house, a symbolic gesture of breaking through years of silence and longing, and she and her loved ones choose to flee together, bound by a shared commitment to stay together regardless of what the truth may eventually reveal.

Amid these emotional upheavals, Takumi makes his way back from the north and finds a place within the family’s renewed life, taking a job at the bathhouse and lending a steadying presence to the household. Kimie, Azumi’s birth mother, makes a return visit, and the bond between the two families deepens in the quiet glow of the bathhouse’s rooms and windows. That night, the five of them—Futaba, Azumi, Kazuhiro, Ayuko, and Takumi—make a late visit to Futaba in the hospital, the group’s warmth and resolve radiating through the sterile walls. In that hushed moment, they promise to keep their fragile, blended family intact no matter what comes after Futaba’s final days, a vow that speaks to a common understanding: love, when shared, can outlast illness, absence, and unanswered questions.
