While Yoshida does his level best to hide it, Mishima and Hashimoto can tell he’s devastated by Sayu’s imminent departure, and how he’s mitigating it by trying to bury himself in his work. While he has many reasons to worry about the welcome Sayu will received from her mother upon returning to Hokkaido, her big brother Issa isn’t one of them.
Issa meets with Yoshida after work to bow in apology for the rude things he said the other day, while also asking him earnestly to continue taking care of Sayu in the time they have left together. He reveals how Sayu was their mother’s last best chance to keep their womanizing dad around, refusing to get an abortion. Alas, the asshole left them anyway.
Sayu’s mom wasn’t equipped to love a girl who was the symbol of her failure to keep the man she loved in her life, and so Sayu received no parental love whatsoever, something Issa believes every child needs. Honestly, it’s a wonder Sayu isn’t a lot more scarred.
While it’s nice to be reminded that Sayu’s brother is a legit good guy, if what he’s said is true, Sayu’s mom may simply be incapable of loving Sayu—or if she does love her on a fundamental/biological level, has never been able to express it. Why would that change when she returns home?
Later, Sayu presents Yoshida with a parting gift: a hand-written and illustrated cookbook with all of his favorite dishes she’s made for him over time. I couldn’t help but let out a loud awwwwwww that a roommate must’ve thought was me reacting to a cute puppy video. It’s such a cute, warm gift, and filled with love.
Sayu’s next parting gift is to share with Yoshida the view Asami shared with her, along with the wisdom she imparted about how even the tiniest stares have pasts and futures. Asami accepted Sayu and became her first real girl friend, just as Yoshida took her in with only the best intentions when everyone before had the worst.
Sayu doesn’t see Yoshida as simply “some guy who shared his apartment with her” for a while. That she met him when she did may well have saved her life, and she’ll never forget that, looking back fondly on the time she stopped running away, settled down, and found a way back.
Sayu admits that she’s tried to leave a few times while Yoshida wasn’t home, but has been unable to do so. Ultimately, he means enough to her not to want to leave without saying a proper goodbye. Because in all honesty, she kinda wants to stay with him forever. But she can’t settle her past unless she goes home.
Ichinose Kana does some really lovely voice work here, and has indeed done much of the heavy lifting in a show that doesn’t have the best production values. She even moves Yoshida to tears, because a part of him doesn’t want her to leave, both because he fears what might go down in Hokkaido, and because he’s become so accustomed to her living with him. He’d no doubt say she saved him just as he saved her.
Back at work, the ever-practical Mishima, independent of her individual crusade to win Yoshida’s heart, says if it’s so unbearable to say goodbye to and part with Sayu, then mabe he shouldn’t, and should instead follow her to Hokkaido. Sure, it would mean leaving his job, but both Mishima and Hashimoto doubt he considers his job or whatever project he’s working on to be anywhere near as important to him as Sayu.
In fact, it pisses Hashimoto off to no end that Yoshida tries—badly—to pretend otherwise, like when Asami calls him saying Sayu has disappeared and isn’t answering her phone. It takes Hashimoto telling Airi that Yoshida are feeling sick and going home early, and Mishima taking over Yoshida’s work for the day, to get him out of there.
While giving him a ride, Hashimoto expresses to Yoshida how it pisses him off that his best friend knows what to care about the most, but pretending he doesn’t. As his best friend, Hashimoto knows what Yoshida won’t admit: wanting what’s best for Sayu, or wanting whatever will make her happy, and his own fear of being apart from her aren’t mutually exclusive.
Sayu is fine (don’t scare me like that, show!); her phone simply died while she was waiting outside Yoshida’s office to surprise him and see where he worked; he and Hashimoto must’ve just missed crossing paths with her. Airi and Asami are there with her, and Yoshida acts like a worried dad when he sees her. This marks the first time Hashimoto lays eyes on Sayu, and seeing her makes him immediately understand why Yoshida is scared of losing her.
That night, the very last night together in Yoshida’s apartment, Sayu asks if she can climb into bed with him. Not for anything weird, but just for some warmth and human contact between two people who have come to mean much more to each other than they’d initially expected.
Sayu asks if she’d have grown up into a “normal girl” if Yoshida had been her dad. Yoshida should’ve answered by saying there’s nothing abnormal about her, she’s a lovely person who has admirably hung in there under abnormal and suboptimal circumstances. Okay, maybe that’s a little too wonky for the mood of that scene.
But whether he had decided earlier that evening, or right there in that bed, Yoshida tells Sayu he’ll come to Hokkaido with her, to keep an eye on her and see her mom with her. Sayu can’t contain her elation upon hearing those words. There’s nothing wrong with going back home to settle your past, but there’s nothing saying you have to do it alone…particularly if you’re someone who’s experienced enough loneliness for a lifetime.
