Anger remained anger, and the desire to immediately separate that Lewd Couple, tie the man to the bed, and hang the woman in the sky, was also real.
However, Sora possessed a Very Sensitive Heart. Her intelligence was not fooled by such cheap tricks. Instead, she more or less saw the bad nature of this adult elder sister before her.
Don't underestimate a hikikomori.
Although it couldn't be said that she had Extensive Experience in Spectating, at least most of her time was spent at home playing games or watching anime and light novels. She had mastered various tropes, and could even develop them.
For example, the act of holding one's chest to accuse another, a similar scene once appeared in a "Cool Wannabe School Style" light novel a few years ago. The female character leading that scene also had large breasts. Thinking about it was truly annoying... Ahem, that's not the point.
The point was, from her expression, dialogue, to her movements when her chest was grabbed, Haruno had no intention of hiding it at all. It was clear she deliberately displayed this trick.
As for the reason, perhaps it was just for fun?
Sora knew that in this world there were people called "Pleasure Monsters"—they could do all sorts of things that Harmed Others without Harming Themselves for that little bit of pleasure, and rarely considered the consequences of their actions. They were fanatics who prioritized pleasure and had twisted personalities.
It was clear that the adult woman currently clinging to her older brother was such a person.
An ordinary chest grab certainly meant nothing to those who had just been hugging at the entrance. As long as Haruno paid the price of Sora's enmity, she would gain the pleasure of seeing these siblings turn against each other and a Love Battlefield immediately ensue. This deal seemed very advantageous—the woman must have thought so.
(Too bad, I'm not as pure and weak as I look... That Poisonous Heart of yours, in front of me, is just a Futanari Book disguised as a Femboy Book. I can see it in an instant!)
Sneering inwardly with disdain, Sora suppressed that Boastful Sense of Superiority, and on the surface she continued to pretend to be very angry, glaring coldly at the Lewd Couple before her.
They sat side-by-side on the sofa, heads bowed obediently, like death row inmates ready to accept their punishment, submitting to her who was full of dignity, serious-eyed, and cold.
"Is there anything else you two want to say?"
As if she was the center of the entire living room, Sora folded her arms across her chest, her gaze sweeping over both of them, and finally stopping on her brother's face.
"It's one thing to bring a girl home on the first day of winter break, but you even committed that Indecent Act at the entrance without regard for others... Yuu, I'm very disappointed in you."
"Wait, why does your tone sound like mom's... What kind of Indecent Act is a brief hug? The anime you usually watch all goes beyond that..."
After calming down from the sudden shock, Yuu honestly bowed his head acknowledging his mistake to his sister, but still mumbled in disagreement.
"Dare to talk back!"
With wide eyes, Sora slapped the table, glaring at him sharply.
However, her bark was bigger than her bite. Fearing pain, of course she wasn't foolish enough to pit her small, white, and tender hand against a hard glass table. Most of her strength had already dissipated upon impact with the table, so the slap didn't look threatening at all.
"Just think, if one day I brought a man home and did the same thing as you, what would your reaction be!"
Yuu immediately pulled back all his expressions. His Eyes Emitted a Cold Glint, his Hands Shaped like a Knife passed across his neck, his tone filled with murderous intent: "Of course I'd kill that man, then take you far away."
Sora Puffed Out her Cute Small Chest, raising her eyebrows like a victor: "So?"
"You're right, I'm just a Lewd and Perverted man, let my sister decide the punishment..."
Yuu covered his face, completely defeated.
Haruno patted his shoulder. She could understand Yuu's feelings of doting on his sister, but that didn't stop her from teasing him with a playful look while comforting him.
Sora immediately turned her sharp gaze to Haruno.
"My turn?"
Realizing that the atmosphere had changed direction, Haruno turned calmly and gracefully. Her smile was gentle and mature. The Majestic and Grand Queen aura of an older sister suddenly emanated, enveloping Sora.
"Yuu-chan always talks about his most important family. I'm almost tired of hearing about you... But, this is the first time we've met formally after I've been dating him for so long."
Her voice was cheerful and gentle, completely different from the Full Green Tea Aura that radiated earlier. She tilted her head slightly, showing a bright and friendly smile to the silver-haired girl in front of her.
"I'm Yukinoshita Haruno, your brother's girlfriend. Nice to meet you!"
"His family is my family. If you need anything or need help, you can tell me. From now on, let's get along well~"
As if a great sun had risen, that Majestic and Grand Queen Aura dispelled all pretense and shyness, appearing naturally before Sora.
Although she knew Sora was a brocon, Haruno remained calm, not avoiding her, and approached her with good intentions.
However, such an attitude exceeded Sora's expectations, making her a little flustered.
"You..."
(Why is her reaction completely different from others caught cheating? Shouldn't she show a little awkwardness or shame when meeting future family?)
Sora screamed in her heart, but in the real world she could only stammer.
Seeing the college student's bright and sincere eyes, Sora slowly lowered her head.
For some reason, the complaints and dissatisfaction in her heart slowly melted like snow under the sun.
Although hesitant, she didn't want to just give in to the evil woman outside—this situation was different from Yuigahama and the flat-chested, black-haired Yukino back then. Although not as bad as the silver-haired Obsessive Girl from before, still, someone was once again going to steal her only family, and build another family without her.
Sora felt afraid because of it.
Although she knew, she absolutely couldn't stop her brother from making the choices he wanted, or destroy the happiness he wanted to achieve.
So, she could only vent her anger within permitted limits, becoming a stubborn yet mature younger sister.
"...Nice to meet you."
Taking a deep breath, Sora uttered this sentence in a slightly stiff and awkward tone.
However, before Yuu could smile in relief, Sora looked at Haruno with serious eyes, and continued in an alienated and sharp tone: "But I'm sorry, for now I can't accept you, let alone consider you part of another family."
"You must be the same. Your mouth is so enthusiastic, but if you really wanted to get along with me, you wouldn't deliberately play that awkward trap scene in front of me."
Her childish and cute face now showed maturity and calmness beyond her years.
Haruno was slightly surprised, raised her eyebrows, then propped her face with one hand, swung her legs casually, and said to her with a friendly smile:
"Oh, you care about that? Then I apologize to you. Sorry, I didn't mean to target you."
"What..." Sora widened her eyes slightly.
"Even to my own sister, if the time and my mood are right, I would do something like that in front of her too... Maybe even worse."
(Well, her personality is indeed unpleasant.)
Sighing, as if deeply reflecting on herself, she shook her head. Then, she turned her serious gaze to Sora, and said firmly:
"I understand. This somewhat malicious part of my nature, for your sake and for Yuu-chan's sake, I will try to improve it in the future!"
Yuu couldn't help but interrupt: "What do you mean 'somewhat malicious'? Aren't you ashamed to say something like that?"
With a single pat, Haruno covered Yuu's mouth with a smile.
"Stupid Yuu, why are you interrupting a girls' conversation? Can't you interrupt in the bedroom... Wait, pretend I didn't say that. I shouldn't Make Vulgar Jokes in front of your sister."
"It's too late!"
"So Sora-chan, please be patient... From now on, through our interactions, I will show my sincerity!"
"Pretending as if nothing happened?! That's the most insincere thing."
"Tsk, Yuu-chan is so noisy. Are you trying to prevent us two from getting along well? If so, I'll also try my best to prevent you from approaching Yukino-chan, you know?"
"Huh? I wasn't thinking that at all! Besides, it's clearly you who made Vulgar Jokes to her sister first. It's rare to find someone with such thick skin..."
"This is all acting, you know. Actually, in my heart I'm already ashamed and screaming, huhu~"
"..."
Seeing the two people on the sofa before her, ignoring her, interacting with natural smiles and familiar gestures.
Sora slightly lowered her head, silent for a moment.
Suddenly, she lifted her gaze again, and said to Yuu in a strange tone:
"This is completely different from last time. If that wasn't acting..."
"Yuu, have all your girlfriends recovered their memories?"
This statement shocked the two people who were Getting More Excited Talking, their faces full of surprise.
Then, they simultaneously turned their heads, looking at the silver-haired girl who was slightly frowning with a strange expression, their voices still filled with lingering astonishment.
"Sora, don't tell me you... still remember about the last task?"
