Episode 3 of "Beyond Goodbye" resumes its narrative on the serene platform, where Kazu's coffee works its magic, soothing the frayed nerves of the gathering. Kazuma and Saeko stand in awe, mesmerized by the breathtaking scenery, while Kazu radiates optimism about their journey. He remarks on their fortune in stopping here, revealing vistas that would otherwise remain hidden from their everyday lives. A sly inkling crosses Kazu's mind that they might have crossed paths before, but Saeko, spooked by his suggestion, mistakes it as a clever attempt to engage her in conversation. She withdraws into herself upon boarding the train once again, immersing herself in her work, leaving Kazuma hanging.
Meanwhile, at the factory, the team brainstorms a revolutionary coffee brand destined to astonish customers, and Shinoda approves with enthusiasm. Saeko finds herself reflecting on her encounter with Kazuma, regretting her harsh demeanor. Conversely, Kazu returns home, absorbed in his coffee machine. Miki, observing his newfound fascination, joins him in cleaning its intricate parts, though a hint of concern flickers in her mind—fearing that his evolving tastes might extend to disliking what he once cherished, including her.
Kazu, indeed, is undergoing a transformation, and Miki senses it keenly. Always a reservedgeek, constrained by his heart condition from engaging in ordinary pastimes like running, his bond with Miki was once enough. Yet, she now worries that his cheerful demeanor might signify a shift from the man she fell in love with.
As their relationship starts to fray, the bond between Saeko and Kazu blossoms. Saeko apologizes for her abrupt behavior and introduces herself properly, sharing insights into her profession. Over cups of coffee, their connection deepens, culminating in Saeko offering pointers on brewing—a necessary gesture since his platform coffee left much to be desired.
Time elapses, and the two continue to grow closer, sharing train rides filled with camaraderie. Kazuma offers thoughtful advice for Saeko's upcoming birthday, hinting at playful methods to distribute gifts and foster joy among all. Kazuma feels something profound but struggles to articulate it.
Miki takes Kazuma along to the orchard, but both he and Saeko are plagued by concerns over their absence from each other's company during the train ride. Suddenly, Kazuma finds himself struggling to catch his breath, culminating in a harrowing panic attack on the roadside, his cries echoing to the heavens. Ironically, the very road they traverse is the same one where Yusuke and Saeko had narrowly escaped an avalanche.
On the train, Saeko's thoughts inevitably drift back to those harrowing moments, overwhelming her to the point of tears as she drifts into a sorrowful slumber. Hiro's voice breaks through her reverie as he rings from outside, offering comfort by suggesting that such dreams are often a sign of those who have departed coming to visit. He gently reassures Saeko, urging her to press on and trust her heart. With a soothing tone, he conveys his belief that she will be alright and that everything will unfold just as it is meant to.
Meanwhile, Kazuma returns to the hospital, realizing with a shock that the thoughts and memories flooding his mind belong to Yusuke. Confusion and fear grip him as he struggles to comprehend what is happening, terrified that he might be transformed into a different person from who he once was.
