Even though today was a rest day, Kojima Kana wasn't slacking off; she insisted on preparing breakfast herself.
Originally, she'd planned to offer Shirase Haruto a personal "bedside wake-up service," but unfortunately, he'd already woken up on his own, leaving her somewhat disappointed.
"So, what are your plans for today? It's the weekend after all; you won't be spending the whole day cooped up inside like before, right? Kirisu-sensei already warned me that she's keeping an eye on you. If you ever push yourself too hard, she'll be calling me right away."
During breakfast, Kojima Kana—casually dressed in a white blouse and pink pajama shorts—was the first to break the silence.
When women with beautiful legs wore shorts like these, it always perfectly emphasized the contours of their legs.
And Kojima Kana happened to have a particularly lovely pair of legs.
Slim, graceful calves, and thighs soft yet full enough to captivate.
Such legs were certainly more appealing than those skinny "chopstick legs" praised online.
Of course, as a woman, her best assets were actually her hips and waistline.
As for her chest?
She could easily take on 10 Kakash—Yukinoshita Yukinos!
"I'll head to the club activities this afternoon," Shirase replied.
"What?" Kojima Kana froze for a moment, thinking she'd misheard him.
Shirase smiled slightly. "I didn't really participate much before, but from now on... hmm, I guess I'll be joining in more often."
"Has the Soccer Club ignited the fiery passion of your youthful heart?" Kojima Kana excitedly responded, getting carried away by her own words.
"Not really. I just don't want the club president graduating with too many regrets."
"Isn't that exactly what I was saying? Want me to come with you to practice? With your dear Kana-nee cheering you on from the sidelines, you'll definitely feel more energized than usual."
"Are you sure you just want to cheer me on, and it's not because you have no one to go shopping with today, and staying home alone would make you feel lonely?"
"…"
Kojima Kana's face flushed instantly, annoyed and embarrassed. "Do you even understand the prestige contained within the word 'adult'? Just who do you think I am? Kirisu-sensei has already become friends with me! Unless something goes terribly wrong, she'd even agree if I invited her out for drinks!"
Shirase hummed thoughtfully. "With your drinking capacity, I bet you'd start acting drunk after just half a bottle of beer."
"Nonsense!" Kojima Kana glared at Shirase unhappily, yet her expression clearly lacked confidence.
After all, she'd secretly tasted beer before back in the countryside—and she hadn't even managed to drink half of a bottle like Shirase mentioned...
...
At two-thirty in the afternoon, Shirase received a message from Hayama Hayato.
Every Saturday, Hayama Hayato sent out messages to everyone, regardless of whether they'd attend club activities or not.
Just like how the Soccer Club president had tearfully pleaded with Shirase back then,
Hayama—ever the popular, warmhearted guy who never ignored others' expectations—had taken the initiative to invite Shirase into the Soccer Club.
After changing into his sportswear, Shirase came into the living room and immediately saw Kojima Kana sprawled across the sofa, legs stretched out prominently.
She noticed his presence too, and when their eyes met, she deliberately huffed and quickly turned away, pretending to read a magazine.
Shirase's lips twitched into a slight smile, but he didn't say anything.
Just as he was changing into his soccer shoes by the door, another clearly audible "hmph" sounded from the living room.
This time, Shirase couldn't help but laugh. Turning towards her, he called out, "Alright, alright, I didn't say it clearly enough earlier. I really do need Kana-nee's encouragement today, otherwise, I won't have the energy to practice at all."
Immediately, the rapid pattering of footsteps echoed from inside, and Kojima Kana's beautiful figure quickly appeared before Shirase's eyes. Folding her arms and lifting her chin proudly in tsundere fashion, she demanded, "Then shout 'Kana-nee is the cutest and greatest!' ten times right now, and only then will I agree to cheer you on."
"Just once—isn't that enough?"
"Nope."
"Then how about three times?"
"Deal."
"You know, on second thought, I don't feel like shouting anymore. Forget it, you shouldn't come."
"Eh? Hey, wait for me!"
Seeing her hurry back to the bedroom to change clothes, Shirase openly laughed.
And she still calls herself an adult?
Though, admittedly, she was quite cute.
Today, Kojima Kana naturally didn't choose her usual figure-accentuating pencil skirt. Even though that style usually highlighted her charm, for the sake of comfort, she'd decided on casual clothes.
"Let's go!"
As soon as she'd finished changing, she stepped out and immediately hooked her arm around Shirase's. Her loosely fitted pink blouse was pulled taut by this gesture, clearly transmitting its softness to his arm.
Shirase glanced at her casually tied ponytail. "Dressed so casually today—won't it damage your 'Demon Kojima' image if the Soccer Club members see you?"
Kojima Kana smiled dismissively. "How could it? All your onee-san has to do is keep up the usual imposing aura, and they won't dare think anything strange..."
Suddenly remembering a crucial point, she quickly added, "You absolutely can't undermine me later, though! I've worked way too hard to maintain this image. If you ruin it in front of others today, I'll be stuck worrying again about how to manage high schoolers!"
"Got it." Shirase thought to himself, Why would I even bother messing with your image anyway?
Once Shirase had promised, Kojima Kana brightened instantly. One hand intimately wrapped around his arm, while the other rose gently, slender fingers twirling her silky black hair. Her steps turned light and cheerful, causing her ponytail to sway with each bounce.
Noticing her playful action, Shirase spoke up: "Let me play with your ponytail a bit."
Immediately, Kojima Kana released her hair, turning serious. "I'm your onee-san—how could a little brother play with his big sister's hair?"
Shirase countered, "If you lend me your ponytail for a bit, I'll make you snacks this afternoon—guaranteed to be tastier than anything I've made before."
He was confident in this, after all—he'd already received his cashback reward last time.
"Really?" Kojima Kana was still half-doubtful.
She wasn't exactly the greedy type, but seeing Shirase so confident, it was impossible not to be curious.
"When have I ever lied to you?" Shirase retorted.
"You clearly trick me all the time..." Kojima Kana muttered softly, but obediently tilted her head nonetheless, passing her neatly combed, silky ponytail into Shirase's hand.
Watching him imitate her earlier movement, winding her hair around his fingers, Kojima Kana's cheeks turned slightly red. Is this perhaps a little brother's attachment to his sister? Otherwise, why is he imitating me?
Thinking this, she instinctively straightened her back a bit more.
But seeing he hadn't yet let go, Kojima Kana moved even closer to him, assuming an even more intimate posture so he could better play with her ponytail.
After all, your big sister is an adult—I have to take good care of my little brother.
