Once Nagatoro’s big sister, who Naoto calls “Anetoro”, realizes the famous “Senpai-kun” is here, she sees a perfect opportunity to toy with both him and her sister. It’s abundantly clear to her, an adult, that these two are absolutely a couple already, and are just been silly kids about it. Giving Naoto a glimpse of Nagatoro with bed head asking for pudding is a unique gift.
When Anetoro prods and lures her crankly little sister with a deluxe pudding bowl, it’s instructive to Naoto, because he’s able to witness Nagatoro with her defenses down. She can’t toy with him, because she’s being toyed with. The result is that Naoto gets to see a new side of the girl who, if he’s honest, he likes.
Indeed, once Nagatoro whisks him into her room to eat their pudding bowls without her sister’s interference, it’s clear that Naoto is not only ready and somewhat willing to slip back into his normal dynamic with Nagatoro, but can tell more than ever that her schtick is performative and not malicious. Toying with him has always been Nagatoro’s coping mechanism for showing affection.
She’s mortified when her sister sees her feeding Naoto, because she’d prefer to keep her thing with Naoto all to herself. It’s the same deal whenever her friends interfere or pry too much. She’s even willing to tell Senpai more about herself…if he can beat her at the video game they played before, and at which she’s been practicing.
While her improved play and ability to distract Senpai results in two straight wins, the decisive battle times out, and per their bet, the “secret” Naoto wants to learn is Nagatoro’s real first name. Not anything pervy. Nagatoro is caught off guard by the request, but realizes she’s never told him. But when she’s about to, he tells her he’d rather ask her fair and square than force her to by losing a bet. That ingratiates him with her even more.
And then, Anetoro goes and ruins their shit by bursting in and hollering her name—Hayase—and offering to show Naoto some albums of her when she was younger. She 1000% was eavesdropping, because this is surely the first and only boy Hayase has ever brought home, and she is also a Nagatoro, which means if someone can be messed with, you must mess with them!
Before departing, Hayase shows her genuine side first by thanking Naoto for checking on her and hanging out, then switches gears into Teasing Hayase by warning him that she’ll be back at school tomorrow to toy with him anew. Naoto’s comeback—”Have some mercy”, is delivered confidently, because he’s not loathing tomorrow; he’s looking forward to it. Also, now he knows her first name. If he ever needs to get her to simmer down with the aggressive teasing, he’s got that first-name bullet in the chamber.
We don’t have to wait till next week for Hayase to be back at school messing with Naoto, though when she strikes a Bruce Lee kicking pose and Naoto agrees they should go with that for his drawing, she has to hold that pose far longer than she had bargained for. Her thighs start barking at her, but she’s on pins and needles and can’t move. Then she stumbles and starts to fall.
Rather than hitting the ground, she lands on soft, fluffy Senpai. The two blush and scream and separate immediately, but it’s clear Hayase is impressed that he was able to move fast enough (and was bold enough) to break her fall. Of course, she covers that up with more teasing about whether he was trying to “get lucky”.
Then Naoto sneezes, and even before the preview confirmed it, I knew it would be Hayase’s turn to pay Naoto a house visit. After all, she just got over a cold, they just had a lot of contact with each other. It would be weird if he didn’t catch her cold!
