"Tatsu-kun, school time—get up already!"
Early in the morning, Eriri's loud voice ruined his precious sleep-in.
Haruno and Tatsuki both opened their eyes at the same time.
Meeting her gaze, Tatsuki lightly kissed her lips and asked gently, "You getting up too?"
Haruno's eyes narrowed in bliss. "Mm, I am."
Like a lazy little cat, she stretched out her arms and said coquettishly, "Tatsu-kun… carry Yukino-nyan out of bed."
"!!!"
Tatsuki's heart jumped.
He'd heard that line way too many times last night—especially with Haruno still wearing Yukino's clothes.
Tatsuki could say with absolute certainty that because of that sentence alone, his combat power had already hit its peak.
Sensing the change at the root of him, Haruno curled her lips seductively and teased, "Tatsu-kun, do you not want to go to school today? Yukino-nyan will satisfy you, meow~."
"Ugh—!"
The moment he realized things were about to get even more out of hand, Tatsuki sucked in a sharp breath and hurriedly stopped her.
"Stop, stop. If you keep that up, we really won't be going to school."
"Get up already, idiot Tatsu-kun—me and Yukino have been waiting for you forever!"
Eriri came charging in like a whirlwind.
Tatsuki turned back with a light smile. "I'm getting up right now. I was a bit tired yesterday, so I slept in."
"Good morning, Eriri."
Haruno looped her arms around Tatsuki's neck—no attempt to hide anything—and calmly greeted Eriri with a relaxed, half-lidded smile.
"..."
Eriri stared at the two of them… and at that faintly visible connected spot.
She saw everything, and it made her temples throb.
Clenching her little fang-like tooth, she turned and stormed out, tossing back one line. "Idiot Tatsu-kun, hurry up!"
But the moment she turned around, she was muttering in her head. "Damn it! Why is Yukino's sister also built like a freakin' dairy cow?!"
She lowered her head and glanced at herself, then started doubting what her mom had said.
Mom said that as long as Tatsuki helped her more, she'd definitely grow.
At school or at home, she asked Tatsuki to help her every day. So why wasn't it working?
Only when she reached the doorway did she remember Yukino was still waiting.
And when she saw Yukino, something suddenly clicked.
Eriri pointed at her in disbelief. "You knew your sister was inside?! Is that why you didn't go in to wake Tatsu-kun and made me do it?"
Yukino pretended she didn't hear, but her eyes kept flicking toward the room.
Tatsuki really wanted to stay buried in Haruno's gentle paradise—especially that -warm, softly chest of hers, but he had to go to school.
Not long after…
Haruno and Tatsuki walked out together, her arm still hooked through his. Haruno was dressed casually now, with a small shoulder bag in her other hand.
When she met Yukino's gaze, she smiled brightly like sunshine.
"Aww, Yukino—your clothes really saved me last night. I deeply felt just how much Tatsu-kun loves you."
As she spoke, Haruno suddenly stuck out her soft pink tongue and licked her lips like she was showing off. "Tatsu-kun was… sooo excited."
"W-what!"
Eriri sucked in a sharp breath off to the side.
Tatsuki and Haruno's banter was normal couple stuff, and it was the same with Yukino too, but when those words came out of Haruno's mouth, it instantly turned into a classic hentai-doujin scene!
The vibe was like Yukino was getting NTR'd right in front of her—Eriri was stunned on the spot. You could even do that?!
Crk-crk-crk!
Freezing cold exploded off Yukino, and the air congealed into icy grit that clattered onto the floor.
Her expression was dark as hell—Haruno's words had clearly set her off.
"Ahem." Tatsuki cleared his throat, awkward. "Haruno, what are you saying…"
The one enjoying it was obviously the two of them, and the one who'd ended up with the ahegao face was Haruno. If anyone was going to say "so excited," it should've been him.
So why the hell was she the one saying it?!
"Tatsu-kun, do you really like Yukino-nyan that much? Nyan~!"
Haruno was fully in actress mode, rubbing against Tatsuki like an actual cat.
"..."
Yukino's face turned even darker—so dark it was scary—and her voice dropped to an icy, cutting chill.
"Then I would like you to wash my clothes properly, Onee-san. Ideally, don't leave even a trace of your scent."
"Aww, Yukino, you're so heartless. We're sisters—good sisters, aren't we?"
Eriri blinked, not daring to say a single word.
She could feel the gunpowder in the air between Haruno and Yukino.
And Yukino's sister looked like the kind of terrifying woman who'd toy with you for fun. To avoid getting burned, Eriri instantly became a background character.
She shot Tatsuki anxious looks, basically asking: Tatsu-kun… they're not gonna fight, right?!
Tatsuki gave her a reassuring look back. "Relax. I'll step in."
Tatsuki let go of Haruno's hand, took Yukino's hand instead, and performed a seamless handoff. "Haruno, we're heading out first."
Haruno's expression turned gloomy. That mouth that had made the root of his trouble feel sweet and warm all night long now puffed up into a pout as she complained, "You really are a bad man. Abandoning Yukino-nyan already?"
"…" Yukino's glare was sharp enough to stab Haruno a thousand times over.
Just hearing "Yukino-nyan" from Haruno's mouth was already driving her crazy.
And Haruno said it so smoothly—who knew how many times she'd said it last night?
If it was her sister… Yukino fully believed she could do anything.
"Pfft—!"
Haruno saw her teasing hit the mark, and adorable Yukino made her laugh out loud.
Wiping away tears that weren't even there, she put on a pitiful tone. "Go on, go on."
"Hurry, hurry! We're gonna be late!"
Eriri decided this place was bad luck and bolted on a flimsy excuse as she dragged the other two to run.
When it came to Haruno, she was kinda scared too. It felt like she could get played in the palm of that woman's hand at any moment.
Just look at Yukino—normally such an untouchable ice queen—yet in front of Haruno, she was getting handled with zero ability to fight back.
Eriri successfully prevented a war, and Tatsuki silently gave her a thumbs-up.
The three of them entered the elevator, and the doors slowly started closing, but right at that moment—
Haruno smiled like a devil.
"Oh, right. Yukino—Big Sis is going home today. I'll have Mom wash your clothes for you, okay? I'm sure Mom will be delighted."
"!!!"
The elevator doors shut.
Through the narrowing crack, Haruno caught sight of Yukino's eyes widening—violent waves of emotion rolling through them.
"So fun, Yukino."
Getting to see Yukino make such entertaining expressions every day gave this hardcore siscon massive psychological satisfaction.
Tatsuki satisfied her body too—maybe that really was what a happy life looked like.
She glanced at the clothes inside her shoulder bag, her eyes glittering. "I said I would… and I meant it. Heehee."
