I really don't want to have a girlfriend.

"Well, anyway, we're both back to how we were before. Let's save the remaining feelings, things we want to say, and complaints for when we're alone in our rooms next time."

"What a surprise, you actually managed to hold back..." Yuu Tenkuji exclaimed unconsciously.

No sooner had she finished speaking than she let out a suppressed laugh.

"Pfft... It's not that I can hold back, it's that I know how to be considerate of my boyfriend."

The pair of bouncy and warm things behind him trembled twice as he tried to suppress a laugh, and then the fair hands that were wrapped around his chest suddenly moved up and cupped his cheeks.

"Come on, little Youyou, look over there!"

"what?"

With a puzzled look on her face, she looked towards the stairwell, following the force of her hand.

"..."

There stood a white-haired, ghost-faced girl with a terrifying expression.

She forced her emotionless eyes open, her slender arms mechanically raised like a puppet on strings, and then placed her thumb across her swan-like neck, slowly drawing a horizontal line towards her brother.

Anyone who sees it will understand that it undoubtedly means "You're dead."

"Qiong... well... let me explain..."

The boy's reflexive words made the atmosphere even more somber and tense.

Before this entrance hall, which felt like a battlefield with a chilling atmosphere, only one person's lips trembled slightly. Then, unable to contain his overwhelming joy, he burst into a hearty laugh.

"Hahaha, I'm so sorry! I really didn't expect it to turn out like this before I hugged you. I really didn't mean to hurt you, little Youyou!"

Behind the frozen Tenkuji Yu, Yukinoshita Haruno couldn't help but slap his back hard, laughing wildly and gleefully, disregarding her image.

Her laughter was crisp and cheerful, as if it could reach the ears of the neighbors, penetrate the soil buried deep in the snow, and soar into the sky after the first snowfall.

She laughed like that, oblivious to everyone else, as if she wanted to laugh out all the air from her lungs.

Because her back was to Yuuki Tenkuji, no one could see Yukino Yukinoshita's expression.

She looked up at the clear, white clouds drifting lazily in the sky with a bright smile, and couldn't help but sigh—it had been so long since she had laughed so happily, and her lips and cheeks felt a little sore.

Yang Nai rubbed her cheeks, wiping away the tears from the corners of her eyes, pursed her dry lips, and gradually relaxed her body.

And all the weight accumulated from the past is now pressing down on his back.

'I knew it; my tragedy wouldn't last forever.'

With a sigh of relief, Yukino Yukinoshita slowly closed her eyes, basking in the warmth of being back to back and heart to heart.

'Although I feel like I didn't do anything, his feelings have inexplicably returned... But who cares? As long as it's to my advantage, that's enough. I'll find out the rest when I have time.'

That being said, how long has it been since I felt this sense of peace when something false becomes reality?

It seems like only a few months have passed, yet it feels like years have gone by.

really……

From summer to winter, I still love him just the same!

"Hmph~"

A smile involuntarily crept onto her lips again. Yukinoshita inhaled deeply the fresh, invigorating air, and silently smiled at the sun-drenched streets after the snow had melted, saying:

"It's amazing that we've managed to hold on until now!"

"Welcome back, my little Youyou."

Chapter Six, as always, is filled with subtle schemes.

Not wanting to appear in front of "outsiders" in disheveled clothes, Kasugano Sora went upstairs to change first, leaving Tenkuji Yu to sit obediently in the living room, waiting to receive her sister's righteous judgment.

She verbally agreed, but Tenkuji Yu had no intention of obeying. As soon as she went upstairs, she picked up the bag and headed straight for the kitchen, first sorting the ingredients and putting them in the refrigerator.

Yukino Yukinoshita naturally followed, placing her hand on his shoulder and lazily clinging to his back like a koala, peeking out to watch him organize the refrigerator.

"Wow, so much stuff! Are you planning a banquet?"

“Yeah, I’m planning to have a Christmas party at home tonight.” Yuu Tenkuji said casually, “If you want to come over tonight, you’d better get on good terms with your future sister-in-law first… She probably doesn’t know about the mission yet, and she doesn’t remember me two-timing, so she’ll probably be just as strict with the women around me as she was with Ryou.”

"Oh, are you doubting my sister's power?" She reached her arm around his front and teasingly lifted his chin. "When it comes to younger sisters, is there anyone in the world more troublesome than Yukino?"

"I can't refute that... If you know what's going on, then I won't say anything more."

"Well, on another note, if I and your sister fell into the water at the same time, who would you save first?"

"???"

This death came so suddenly!

Tenkuji Yu almost choked on his own saliva, then reached back and slapped her plump, round buttocks in an annoyed tone: "Of course I'll save both of you at the same time! I don't have the habit of prioritizing important people. No matter how many people fall into the water together, I'll risk my life to save you all first, okay?"

Yukino Yukinoshita poked his cheek, her attitude seemingly relaxed, but her nails gradually increased the pressure as if she wanted to leave marks on his face, saying, "What an unsurprising answer... Are you sentimental or just a womanizer? It's one thing to value family, but does your 'you all' include girls other than me?"

As soon as she finished speaking, her fingernails landed on his neck, lightly scratching his carotid artery.

It was almost like torture—even though she knew she wasn't serious, Yuu Tenkuji still felt a chill run down her spine and was somewhat terrified.

Even so, he didn't intend to give her a perfunctory answer or lie to her; he would only give her the answer that would make her angry.

"Don't you remember what I said to your mother? It wasn't just about two or three people, but about the 'girlfriend' category. Whether it's you or Yukino, I won't give up on you."

Like a stubborn young man who knows his mistakes but refuses to admit them, Yuu Tenkuji said without hesitation, "I'm sorry, Haruno, but now I can no longer be as devoted as I used to be—I will do my best to make the people who are willing to stay by my side happy."

Yukino Yukinoshita continued, "And if someone doesn't want to accept you having a group of girlfriends, would you send her away and wish her happiness?"

"..." Tenkuuji Yu was silent for a moment, then sighed and said in a low voice, "Logically speaking, that's how it should be done. After all, I'm already planning to have multiple relationships, so if any of them don't want me to take them, I have no right to force them to stay. This isn't about right or wrong; I'm not some nouveau riche who abducts women. No matter how shameless I am, I can't do something like that..."

Yukinoshita lifted herself off his back and asked in an emotionless voice, "So, you really intend to let go?"

Tenkuji Yu turned around, took her cold little hand in his, and smiled brightly: "So, before I have to let go, I will hold the hand I don't want to let go of."

"Then I'll let go anyway." She pulled her hand back with a cold face, but she didn't use much force at all. Like a spinning top with its string pulled off, she was quickly pulled into Tenkuji Yu's arms and the kitchen door was closed behind her.

Yukino Yukinoshita tilted her head back, her fingers blocking his lips as he tried to kiss her, and looked intently into his eyes: "Knowing what a scumbag he is, why don't you leave him? That's just the girl's own fault for being too stupid, I have nothing to say... However, I won't easily give up my plan to have you all to myself."

"Since I've already missed the best opportunity to stop you, from now on, I will correct you in order to win all your love, until you swear that you will only love me... I'm not a very generous woman. Yuu-Yuu can only be mine, and I won't even give her up to Yukino."

Yuu Tenkuji shook his head, his eyes equally resolute: "You can't do it, because I won't let that happen. To only like one person means I have to reject others... Just like last mission when I rejected you and hurt you for Yui and Yukino, doing so might be the right thing to do, but it's not the future I want to see."

"So, I won't repeat the same mistake... I'm a very selfish man, and even if it means you have to share your little Youyou with other people, I won't hesitate at all."

Yukinoshita withdrew her fingers and instead grabbed his collar, her moist, soft lips curving into a defiant smile that was both angry and unwilling to back down.

"Fine, let's see who has the last laugh, you damn womanizing boyfriend."

This is also a test, a test that the two set for each other's views on love.

In the past, he passed the trials and became Yukino's hero; now, it's her turn to pass the trials and become Yuu's only girlfriend.

Before Tenkuji Yu could answer, the female college student pulled down his head and kissed him fiercely like a wolf.

With his head down, Tenkuji Yu took out a coin from his pocket and flicked it forcefully towards the sink.

The faucet was forced to raise its proud head, and the water jet gushed down, the sound of splashing water immediately drowning out the panting that followed, and a strange and ambiguous fragrance gradually filled the air.

After a long while, the two finally let go of each other and began to tidy up their messy clothes and hair.

As she turned off the tap, Tenkuji Yu casually asked, "But then again, during the cultural festival, you clearly spoke up for me, using the argument that 'it's normal for important people to have multiple wives,' and convinced your mother to accept the fact that I was two-timing her, right? So why are you still..."

Yukinoshita rolled her eyes at him.

"Are you stupid? Logic is logic, and polite words are polite words. If I were in your shoes and my husband was being intimate with other girls every day, the first thing I would do is castrate him. Who cares if it's normal or not? And don't you know that girls are hypocritical?"

"That makes sense, I understand now."

"Don't worry, I won't castrate you before our child is born."

"What kind of peace of mind do you expect me to have?"

Yukinoshita glanced at him slightly, her cold gaze seemingly condemning him silently.

But then she suddenly smiled, gave him a hard kiss on the cheek, and gently hugged his arm.

"Just kidding~ I know your difficulties, why would I do something so hurtful to you~"

Tenkuji Yu's face was full of disbelief: "Come on, your feigned retreat won't work on me. I've seen through all your moves..."

"Oh? How about this?"

A wicked smile flickered at the corner of his mouth, then vanished in an instant.

Before Yuu Tenkuji realized something was wrong, Yukino Yukinoshita suddenly grabbed his arm and placed his large hand directly on her chest, as if she wanted to forcibly imprint a handprint on it.

Then, turning her head in surprise, she looked at Kasugano Sora, who was slowly opening the kitchen door with a blank expression and staring at them with cold eyes. A little shy and blushing, she pouted and complained to him in a coquettish tone:

"Ugh, I told you not to do that kind of thing in the kitchen! Youyou, you're such a jerk!"

Yuu Tenkuji: "..."

Chapter Seven: The Formal Meeting of the Sister-in-Law and the Sister-in-Law

I was angry, but I also really wanted to tear that despicable couple apart on the spot, tie the man to the bed and hang the woman from the sky.

However, Kasugano Sora was astute and intelligent as a mirror. She was not fooled by such a trick and instead saw through the wicked nature of the mature older sister in front of her.

Don't underestimate those who stay at home.

While she can't be said to have watched countless films, she spends most of her time at home either playing games, watching anime, or reading light novels. She's already very familiar with all sorts of tropes and can even apply them to other situations.

For example, the kind of thing where someone is falsely accused after touching a bear. A few years ago, a light novel with a campus-style arrogance had a similar plot. The female protagonist who was in charge was also a busty woman. It's really annoying to think about... cough cough, but that's not the point.

The key point is that, regardless of her expression, lines, or actions when being petted by the bear, Yukino Yukinoshita made no attempt to hide anything; it was clearly a deliberate performance for them to see.

As for the reason, it's probably just because it's fun?

Kasugano Sora knew that there were people in this world known as "pleasure monsters"—they could do all sorts of things that harmed others but not themselves in order to get that little bit of pleasure, and they rarely considered the consequences of their actions. They were a group of pleasure-obsessed, twisted fanatics.

It's obvious that the adult women who are now clinging to their older brothers are this kind of people.

The mere act of petting a bear was nothing to them, who had just been cuddling in the entryway. As long as they paid the price of potentially incurring her hostility, they could gain the pleasure of witnessing the siblings turn against each other and a chaotic scene unfold. This deal seemed incredibly worthwhile—that's probably what the woman was thinking.

'Unfortunately, I'm not as innocent and naive as I appear... With your venomous heart, you're nothing but a futako-doji disguised as a cross-dresser in front of me; I can see right through you!'

Kasugano Sora suppressed her smug sense of superiority, letting out a disdainful sneer in her heart, and continued to pretend to be very angry, glaring coldly at the despicable couple in front of her.
