After a trippy dream sequence in which Sakura is surrounded by glowing orbs, Sakura is abruptly awakened by Kero-chan, who is curious what she was dreaming about, since a Cardcaptor’s dreams may be premonitions. Unfortunately, she was so startled by Kero-chan waking her up, she can’t remember much!
Kero is also curious as to whether she’s completed her summer homework, as vacation drawing down. Sakura dodges the question by focusing on her dinner duties, but makes sure to stop by Yukito’s on the way home from the grocery store in case he’s home.
As fortune would have it, he is, and he serves her some tea and sweets, totally making her day in the process. While she’s on cloud nine crushing on him, it’s clear Yukito’s many gestures of kindness come from his essential nature; he treats her the way he does because he’s a nice guy…not because he “likes” her romantically. Still, a girl can dream…
With his grandparents traveling, Sakura is worried Yukito is lonely, so when he offers to walk her home (he has something to return to Touya anyway), the Kinomoto siblings invite him to join them for a delicious repast of okonomiyaki. When Touya hears Sakura is attening the summer shrine festival later that evening, he volunteers to tag along, and Touya follows suit.
When they arrive, Sakura resplendent in her sakura-patterend kimono made by her dad (his skill with needle and thread explains a lot of Sakura’s sharp everyday outfits), Tomoyo derives the most fun not by participating in the various festival games, but by recording Sakura having fun. It’s something Sakura’s never been super-comfortable with, but she respects Tomoyo’s wishes.
Also attending the festival are Chiharu and Yamazaki, who we’d already learned were childhood friends, but appear more like boyfriend and girlfriend here. Even when the former is choking the latter out for his elaborate lies about the history of things, it’s clear to Sakura and Tomoyo that the two make a good pair.
Syaoran is also there acing the shooting game, and when he spots Yukito he immediately hands him all of his edible prizes. When both Yukito and Sakura agree that a stuffed rabbit is cute, Touya and Syaoran engage in a heated competition at the ring toss. This allows Sakura to slip away to spend time alone with Yukito.
As they end up in a secluded spot and fireflies start amassing, Sakura deems it a good time to at least attempt to confess her feelings to Yukito. She’s interrupted by Touya and Syaoran—both of them having won rabbits for the two others—and I’m kinda glad she was, as she would have almost certainly had her heart broken by Yukito’s rejection, no matter how much he’d have tried to soften the blow.
Instead, Sakura get to exist in that lovely heady limbo where any answer might’ve been possible, but due to circumstances she couldn’t come out and say anything this time. Furthermore, she comes to recognize the fireflies as the same phenomenon from her dream, meaning Kero-chan was right about her seeing the future.
In a card-sealing that requires no confrontation or fighting whatsoever, Sakura gains the Glow card. Instead of being rejected by Yukito, she had a wonderful day and night. Now, on to that summer homework!
