Adachi is so excited about Valentine’s Day she can’t sleep, but Shimamura confirms she’s still down to hang out, so that anticipation sustains Adachi, as does Shimaura’s face when she first sees it in the morning. Shimamura is her “sun”, after all, providing light and warmth to Adachi even if Shimamura herself considers herself far gloomier than she once was.
The first thing Adachi notes about the day is that she’s acting like Shimamura’s puppy, having to be told to “wait” and “stay” and dutifully obeying. She also thinks being an actual puppy in Shimamura’s arms would be pretty nice!
The second thing Adachi notices is that Shimamura is more bubbly than usual, smiling and laughing at Adachi’s answers and reactions as they hurry aboard a Nagoya-bound train. Shimamura offers Adachi the only free seat and they pass the time playing Shiritori.
While waiting in line for Adachi to buy chocolate, the two thumb wrestle. Then the big moment comes, and…Shimamura bought Adachi chocolate from the same place! Turns out she hung out with childhood friend Tarumi the previous day.
While the two hangout sessions have a lot of similarities, Shimamura’s time with Tarumi, I dunno…lacks a certain sparks that the same time with Adachi has in spades? It’s almost as if so much time has passed, these two just aren’t as close as they once were. The happiest Shimamura seems the whole time is when Adachi texts her to confirm they’re still on for Valentine’s!
At the very end, both Shimamura and Tarumi seem a bit disappointed their time together wasn’t as fun as they imagined, but at the very end Shimamura salvages it somewhat by finally remembering she used to call Tarumi “Taru-chan”.
Back in the present, Shimamura and Adachi try the chocolate, with Shimamura drawing in close and grabbing Adachi’s cheek as a lie detecting method, and Adachi telling Shimamura to say “ahh” so she can drop a chocolate into her mouth.
Then Shimamura ends up doing one of the most surprising things she’s ever done: she arranged to have the LCD sign at the station display a message meant for Adachi, stating “I hope we can continue to be close” followed by her name. Adachi is touched, even though Shimamura admits she chose something “safer” since she doubted they’d be in the right place at the right time.
And yet it’s so apropos that they are, and that it worked out. It’s a clear sign to Adachi that Shimamura does care for her, and not just as a puppy…since dogs can’t read after all! Sure, Shimamura still demonstrates she’s still not quite on the same wavelength as Adachi when she’s genuinely confused as to why Adachi wants to hug her.
But that doesn’t change the fact that she does let Adachi hug her, and it’s not at all an unpleasant experience. Hey, she did want to stay close! As for Adachi, she briefly wonders what others around her think about the sight of them, but ultimately doesn’t care; on that train platform in that moment, Shimamura is the only one she sees.
