Back at school after summer break, Hoshino Kaoru is sporting a new super-short hairstyle, in keeping with her goal to become an otoko-yaku, but soon scolds Sarasa and Ai for allowing themselves to get a tan. Flashback to a formative summer in Kaoru’s life: the summer before her third year of high school, her last chance to get into Kouka…and when she fell in love for the first time.
Kaoru walking on sunny days with an umbrella was derided by some, not only was it odd behavior, but also presumptuous to those who knew her pedigree. While using a bus stop to the hospital to visit her gran (recovering from surgery), she encounters Tsuji Rikuto, the younger brother of a famous rising star of baseball.
Since his gran is so into the Kouka Revue and he overheard from mean girls of Kaoru’s relation, Rikuto works up the courage to ask her about the troupe, but is interrupted by another girl in love with his brother to give him her love letter. He refuses, and shortly thereafter, Kaoru tells him her name.
At first, Rikuto thinks she’s another girl trying to get closer to his bro through him, but she quickly clears that up by telling him about the expectations being the daughter of a Kouka actress and granddaughter of a top star, and he gets it; they’re like kindred spirits.
Of the two, Kaoru is the one more keen to fight against those who would define them by their more accomplished relations, and it’s her texts to him encouraging him to be himself and not worry about being compared that causes an uptick in Rikuto’s baseball play.
Their bus stop encounters and bus rides soon become something both look forward to, such that Kaoru starts visiting her gran more so she can also see Rikuto. She confides in him how she’d never be somebody to say “I’m getting in” knowing how hard it really is (Sarasa doesn’t have that problem). Kaoru is all about the hard work, right down to covering up in the sun to avoid getting tanned.
When she shows off the skirt she’s wearing, eager to wear as many as she can before she gets into wearing men’s clothes when she’s an otoko-yaku, Rikuto is sure that even if she had a mustache she’d be pretty. It’s the first time a boy ever called her pretty, and she wasn’t prepared for how happy it made her.
Rikuto eventually asks Kaoru out to the fireworks festival marking the end of summer; unaware that it would also mark the end of their brief, cozy romance. Before meeting him there, his grandmother assures her she doesn’t have to keep trying to become a Kouka actress if she doesn’t want to.
Kaoru isn’t about to tell her still-recovering gran that she’s full of shit, but she’s still down in the dumps when she meets Rikuto. For a time, him complimenting her yukata catching her when she’s pushed by some kids, and holding her hand is enough to soothe her troubled heart.
But then she asks why Rikuto seems so down, and he tells her that he’s questioning what the point of forcing himself to follow in his brother’s footsteps and fulfill everyone’s expectations of him…then he says he’s sure Kaoru thinks the same way all the time.
Kaoru…does not. Like her gran, and practically everyone else in her life, Rikuto doesn’t understand her after all; that this is precisely the path she chose to walk and she’s never questioned why she was walking it. She’s not trying to get into Kouka for anyone other than herself.
As she runs away from Rikuto in tears, she calls herself stupid for feeling jealous of the “typical high school girl’s life”, including having a boy worry about her and cheer her up. She runs along the beach singing a song, her voice wavering from her flowing tears, but eventually her voice clears as heartbreak turns into iron determination.
She swears to herself she’s going to make it. The normal life isn’t for her. She’s bound for the world of dreams and glamour.
While she intends to make a clean break by blocking Rikuto on her phone, his team actually makes it to the Koshien prelim final, and he just so happens to hit a game-winning pinch-hit home run as Kaoru is walking past a TV in the window broadcasting his game.
Despite knowing nothing about baseball (except what he taught her), and how things turned out at the fireworks festival, Kaoru is still happy Rikuto got to play, and win. Seeing him succeed on TV showed her that he didn’t give up on his path after questioning the point of it all, and after he incorrectly assumed her motives for walking hers.
She still never went back to that seaside bus stop, but it reappears again at Kouka of all places, when Sarasa sees it going viral on social media. Some mystery person left a note on the wall of the stop saying he didn’t give up and thanking another mystery person. Being a hopeless romantic, this kind of thing is right up Sarasa’s alley.
As the newly-shorn Kaoru examines the picture, she smiles knowingly and blushes ever so slightly. Of the thousands sharing that picture, only she and Rikuto know who it’s for and what it means, just like only they know what they want to do in life and are going to go after it with everything they can.
Hoshino Kaoru closes this incredibly moving portrait of her character the way one would close an epic romantic movie: by saying that when she gets to walk out on that Silver Bridge, she’ll save Rikuto “a primo seat in the SS section”…and maybe even say she was in love with him one bright, beautiful summer.
The perfect parting shot of the two having fun at the bus stop by the sea, at the height of that summer and the height of their love, was a thing of exquisite bittersweet beauty—as was the closing theme as sung by Kaoru ‘s seiyu Taichi You. And just like that, I’m in love with yet another character in this show, along with Sarasa, Ai, and Ayako.
