Yui is in a predicament. She was sent to the past to save Kaori’s life, but it wasn’t as simple as keeping her away from the runaway bus. Now she’s finally cracked it, and Sou simply won’t leave her alone.
And then there’s the slightly more pressing matter of…her existence. I’m not sure Future Sou and Airi told Yui, but if she’s successful in saving Kaori, Sou will have never had to create her, so she will cease to exist. That’s not really ideal, because after all this time she’s fallen for Sou and can’t deny part of her wants to be with him.
Whether or not Sou and the others recall even a faint glimmer of having known Yui before she entered their lives (from the previous times she went back and ended up naked in his arms), on this, perhaps the last time she can come back, Yui finally stumbles on the answer to saving Kaori: by having Sou give her a straight answer.
With no other ideas, Yui decides to facilitate that course of events. She can no longer afford to be subtle or clever (and in any case that never worked before) so she just comes out and tells Sou that Kaori will confess to him tomorrow, and that he has to give her an answer. The thing is, after how Yui has acted the last few days, Sou takes this in a much different way than Yui intended. It’s almost a case of unintended reverse psychology.
Kaori reacts the same way when Yui is equally upfront in insisting she harbors no romantic feelings whatsoever for Sou. Kaori isn’t buying what Yui is selling, even if Yui didn’t have possess fragments of Kaori’s memories and personality that come through in her behavior and demeanor.
Kaori can tell Yui’s lying…because she is lying. But Kaori will still confess. No matter what happens, she can’t move forward the way things are. This is also literally true, as every time Sou hasn’t answered Kaori, she’s ended up dead shortly thereafter.
Things go almost like clockwork on the fateful day, but only in where people are, and when. In terms of what’s said to who, things go far differently than Yui imagined. Despite her feelings for Sou, she never imagined his straight answer to Kaori would be a rejection. After all, they grew up together. Kaori has had so much more time with him! Surely he must return those feelings! Well, he doesn’t…and ironically, it’s thanks to Yui.
This time Kaori stays at school while Sou chases once more after Yui, who had done her best to say her goodbyes, both to her friends and to the town. But so flags her down just as the bus arrives. It crashes as before, but Yui and Sou avoid it and survive. The loop has been broken.
It’s here where Sou tells Yui he rejected Kaori…because he really loves her. Yui returns his confession with her own, plus a kiss (get out of the street, lovebirds!), but she knows this is the end for her. Her mission is complete, so she was never created, and she disappears. Put simply, this is time-trippy romantic tragedy done right.
It’s not the somewhat silly kind of ‘vanishing in his arms’ disappearance either, though she does go a bit translucent. Rather, time continues as if she had never been there. Well, almost. The astronomy club finds Sou at the crash site, and everyone thinks very hard about whether everyone is really accounted for. Furthermore, Sou puts his hands to his lips, where a Yui that never was just kissed him.
In every physical form, Yui is gone, or rather never existed…even in the group photo, BTTF-style. But somewhere in the hearts and minds of the others, particularly Sou, a part of her still seems to linger. An absence is felt, even if they know not why. Was Sou’s rejection of Kaori negated? Is Yui well and truly gone? Have we really seen the last of her?
I honestly have no idea what’s going to happen in next week’s finale. I kinda like that!
