So yeah, things are not off to a great start when the first thing Sayu’s mom does upon laying eyes on her for the first time in half a year is slap her in the face. It’s super awkward, and continues to be so, because they’ve entered Sayu’s mom’s castle and she’s in charge. Issa, as much of an independent and successful adult as he may be, still shuts up when his mom tells him to, which is often.
The discussion moves to the dining room, where it becomes clear Sayu’s mom isn’t interested in empathizing with Sayu as the young woman she is, let alone see her as a daughter to unconditionally love. Instead, she immediately airs her grievances, citing all the rumors that have cropped up since she disappeared.
She’s not glad her little girl is home, but still angry she left, because of how it affected her. It’s also clear she suspects Yoshida of taking advantage of her. Sayu does her best to state her case and demonstrate how she’s grown, but her mom has long since developed cloth ears to anything she says, no matter how true or perceptive it may be.
Once she inevitably declares that she wishes she had never given birth to Sayu, which, just fuck you, you despicable c-word—Yoshida, who had been sitting calmly and quietly the whole time, almost picks up his glass of iced tea and throws it in the bitch’s face. But rightly realizing that would accomplish nothing and possibly even hurt Sayu more, he does the opposite.
He calmly speaks from the heart about how just as a parent can’t choose the child they have, the child can’t pick the parent either. The difference is, a parent is (usually) an adult, and thus responsible for their life. Children aren’t. They need to be cared about and for by parents, or they can’t become proper adults themselves. If Sayu’s mom doesn’t want that responsibility, Yoshida would happily take it from her, adopting Sayu and raising her until she’s a real adult.
But he can’t do that, because Sayu has a mom, and she will never not be her mom. So he prostrates himself and begs her to take care of Sayu. Issa follows his lead and does the same. Faced with this unexpected groveling, Sayu’s mom simply freaks out, and Yoshida and Sayu have to leave the house while Issa tries to calm her down.
As Sayu and Yoshida sit outside and wait, Yoshida can’t fight back tears, lamenting just how much worse the situation between Sayu and her mom turned out to be. Sayu is surprised, but also can’t stop herself from crying once she sees him doing it. But it’s a good cleansing cry that transitions into looking up at the beautiful night sky and holding hands in solidarity.
Even though things are not great, they’re going to be alright. Sayu feels forgiven after Yoshida’s groveling, and after making her piece with her friend on the rooftop last week, feels confident in being able to stand for herself. She also admits that things aren’t going to get better with her mom overnight, but neither of them have even given it a try, so that’s really the first step.
Issa comes out, telling Yoshida that bowing before their mom seemed to do the trick. She’ll insist Sayu live there until graduation, and as long as she doesn’t cause problems for her, she’ll “leave her alone.” It sounds like more selfishness and an inability to see Sayu as anything other than a burden and a hassle, but again, we’re at the start of something. Sayu and her mom will have to adopt and entirely new way of interacting with each other, and that will take time.
What’s important is that not only Sayu is willing to put in the work to give it a try, but Sayu’s mom is too. After Yoshida meets with her again to apologize for lecturing her before, she asks if nothing really went on, he answers truthfully, and she seems to believe him. What puzzles her is why he’d go so far for her daughter, to which he can only say “because I met her that night, in that moment.”
Surely Sayu’s mom must understand how something like that might work; she was, after all, presumably in love with Sayu’s father. She simply didn’t know of any way to keep him around other than the hail mary of having Sayu. When it didn’t work and he left anyway, she put all of her scorn into her.
But she seems to finally understand that it can’t go on like that anymore. Sayu ran away to get away from her, but now she’s back, and she’s grown a little more. It’s up to her, the parent, to ensure that growing up is completed. So she’ll talk with Sayu about their future together, however much of it there ends up being, and go from there. And Yoshida will go back to Tokyo in the morning. But it’s a good thing he came.
