Summer uniforms are here, and so are fitness tests. After her “tie” last time, Yadano is eager to defeat her rival Komi. Alas, she can’t even manufacture a tie this time, as Komi wins seven out of seven “events”, despite knowing of no rivalry whatsoever.
Yadano holds out her hand to congratulate Komi on a great challenge. But when Komi doesn’t take her hand, Yadano sees it as a rebuke to Yadano giving up. Instead, Yadano “accepts” Komi’s “offer” to continue their “rivalry”. Those quotation marks are doing a lot of work!
Thanks to their pushy presumptuousness, Najimi invites themselves to Komi’s house with Tadano, and they meet Komi’s mom Suko. Initially she looks like a cool quiet, slightly intimidating lady. Then she reveals she communicates just fine. In fact, she’s proud of how she looks “forever seventeen” and her kiddy enthusiasm mortifies her silent daughter.
Najimi tries to find secrets in Komi’s room, but instead finds books on communication (with both humans and cats!) then leaves the room to watch Komi and Tadano alone in the room. For fifteen minutes, the two sit in silence, frustrating Najimi, but it’s never awkward. Komi and Tadano could sit quietly together for hours. Najimi snaps a candid shot, and Komi is so happy with it she ask her mom if she can buy a picture frame.
When Komi meekly expresses her wish to go out for ramen, Agari, a ramen expert, takes charge. When talking about food, Agari becomes a much more confident and talkative person (until people look at her), and obviously knows her stuff, listing off the various “ramen commandments” one must follow. Komi is able to communicate what she wants to the brawny but similarly tiny-voiced ramen chief, and proves a ramen master, waiting patiently and quietly (natch) and finishing and leaving promptly.
A new friend is introduced in the chuunibyou girl Nakanaka Omoharu, who wants to be Komi’s friend but assigns labels that confuse Komi, which cause Nakanaka to get the wrong idea that Komi isn’t interested in being friends. Just as Tadano is a great Komi translator, he is also well-versed in the chuunibyou/”cringe” lifestyle, having lived it himself in junior high, only to swear it off when his crush rejected him for it.
When everybody is trying to be Komi’s partner for stretching, Nakanaka watches everyone else pair up and sits in on the floor alone and morose. She’s startled but ultimately delighted when she notices Komi had declined all other potential partners to make a “blood pact” with her. Nakanaka may play it cool and say that the pact actually made Komi her “vassal”, but it’s just “friend” by any other name.
As for Tadano, Komi’s most “normal” friend (at least relative to the others), Komi finds excuses to spend time with him, even though they’re rarely apart. When Najimi steals Tadano’s umbrella and it rains after school, Komi is waiting for him with hers, and they end up sharing. It proves a bit too much for Tadano after grazing her shoulder, and offers to hold it between them—getting his shoulder wet, but keeping Komi dry.
Later at the konbini where Tadano buys another umbrella and towels for them to dry off, he asks if Komi saw Najimi’s note and chose to wait, rather than it being a coincidence of timing. To this, Komi simply looks on in silence, and her very aura parts the clouds. For all the various terms Komi’s friends use to describe their association, Komi is clearly Tadano’s sun—and vice versa!
