The day of the cultural festival and its all-important confession session have arrived, and Sueharu is ready to do battle with Mitsuru for Kachi’s heart. But just as Sueharu is causing Kuro to blush by complimenting her cute café outfit, he gets an unexpected visitor: Shirou, the kid he hung out with when he was little.
Of course, we know it’s just Kachi, with her seiyu Sakura Ayane only making her voice a little more boyish. To her surprise and delight, not only does Sueharu remember who she is, but remembers the promise he made to appear in something she wrote. Shirou reveals she is and was Kachi all along, and asks that he call her Shiro, and she’ll start calling him Su-chan again.
Kuro overhears this all, and isn’t ready to give Sueharu up just yet. Sueharu may not have known until now that Shirou was Kachi, but he knows Kuro well enough to know when she’s seeking attention, since she goes off on frustrated rants to him and only him. Everytime Kuro and Sueharu share the screen, you know you’re in for some wonderful character work.
Unfortunately their time together leading up to his big performance ends on a bitter note, as Kuro decides it’s necessary to “hit the reset button” on her and Sueharu’s relationship. She commemorates the moment with a slap, saying whatever he does with Kachi isn’t her concern. Though she runs off, she can’t help but turn back when Sueharu calls her name, and gives him just the saddest, loneliest smile as she wishes him luck on stage.
With that, the confession festival begins, and by God what a cur-sed exercise. Sure, it works out for one guy confessing his love to a girl who feels the same way, but seriously, if this is a real thing in schools these days I’m glad I’m not in high school anymore. I’ll confess to someone in private, thaaaaaanks.
The resulting song-and-dance-off between Mitsuru and Sueharu is suitably anticlimactic. I’m no dance instructor, but it looks like they’re both dancing like Elaine from Seinfeld, and their mouths rarely, if ever, move while they’re supposedly singing. Still, the scene is notable for not going the way I thought, with Sueharu suffering a sudden bout of stage fright and ruining his big chance, as several flags set earlier suggested.
I made special mention of Kuro’s parting smile immediately before his performance because that’s what I believe caused Sueharu to flip a switch of his own, and I’m not talking about going into stage mode. While he woke up that morning intending to confess to Shiro, his interactions with Kuro before and since have finally gelled into the realization that she is the one most important to him.
When Sueharu confesses to Kuro instead of Shiro, it’s a tremendous shock for both girls. Shiro is shook, while Kuro is caught so off guard she impulsively and very publically turns him down, still sore from when he turned her down.
As we learn in the aftermath of this total romantic fiasco when he and Tetsuhiko do the postgame show, Mitsuru wasn’t an asshole after all! Shiro was never dating him; he simply went along with it when she lied and then was too proud to take it back. Mitsuru intentionally chose a song that Sueharu was far better at performing, because he selfishly wanted to see Mitsuru back on stage.
Both Mitsuru and Tetsuhiko did all they could for Shiro and Sueharu, respectively. But when Sueharu changed on a dime who he’d be confessing to, he sealed his fate; Haru was under no obligation to say yes, due to a part of her wanting revenge against him for taking her for granted and pining for Shiro. Shiro, in turn, could have gotten Sueharu if she hadn’t lied about Mitsuru, which caused him and Haru to plot revenge against her.
Finally, Kuro played herself, because in hindsight the satisfaction she got from rejecting Sueharu simply wasn’t worth it. Now she regrets rejecting him, just as Shiro did after learning him quitting acting wasn’t his fault. The timing of all three sucked, resulting in all of them being alone and miserable.
And as complicated as this whole business felt, this is the last time it’s just Sueharu, Kuro, and Shiro, as a third girl is introduced post-credits, discovering her “Onii-chan” has returned to the stage. The messiness has just begun!
