I really don't want to have a girlfriend.

"If it's not too difficult to answer, no problem~ Your measurements are barely acceptable."

"I'm not interested in that," Yuu Tenkuji replied casually, though he hesitated slightly.

"On the other hand, you probably don't have any strange fetishes, right? If you do, please tell me first, because as a 'rent-a-boyfriend,' I have to consider whether to cooperate or politely decline in this regard..."

Although he used this reason, his real purpose was simply to change his mining strategy based on her answer.

This is his 'first mine'. Although he doesn't know how long it will last, he will dig as much as he can and as deep as he can before the mine collapses, squeezing out all the value the system gives him.

The price is nothing more than going out with her and exchanging a few words. No matter how difficult this woman's personality is, Yuu Tenkuji will not give up mining because of trivial orientations such as "sadism" or "masochism".

"Hobbies? Let me think..."

Her pink fingernails tapped lightly on the steering wheel. After pondering for a while, Yang Nai suddenly changed her mind and asked:

"Little Youyou, the one I saw on your phone before, is that your sister?"

Tenkuji Yu was taken aback and reflexively frowned, feeling that she was not going to say anything nice again.

But after confirming that she no longer had the same malicious expression as before, he still cautiously gave his reply:

That's right.

"I also have a younger sister."

At this point, Yang Nai suddenly curled up the corners of her mouth, revealing a smile that was somewhat different from before.

Yuu Tenkuji couldn't understand what she was thinking, nor did he know why she suddenly brought up the topic of her sister, so he could only go along with it:

"Is it... Yukino Yukinoshita from our school?"

"Oh? You know her?"

Yang Nai turned her head and looked him over with interest: "Is she that famous at Zongwu High School? Or are you also in the International Education Class?"

The International Literacy Class, also known as Class J, consists of the children of returning elites and students preparing to study abroad. It is also the class that Yukino Yukinoshita attends.

Yukinoshita Haruno seemed to have known all along that he was also attending Soubu High School, and was not surprised that the two of them were in the same school... Tenkuji Yuu had a reasonable suspicion that she had probably investigated all of his basic information.

After all, the children of legendary prominent families are all so cautious; they will first send their subordinates to investigate the other party's background before deciding whether to develop a deeper relationship with them.

“I’m in the regular class.” Yuu Tenkuji shook his head and said honestly, “I’ve never seen her and I don’t know her, but there shouldn’t be any second-year student who doesn’t know the name Yukino Yukinoshita.”

"After all, he's the top student in his grade, often praised at morning assemblies, and good-looking too."

"Hey~ Is that so?"

Yukino chuckled twice, her voice carrying a profound meaning.

"So, she's only remembered because of her good grades and good looks, and nothing else?"

"Sure enough, they keep saying they want to change, but they haven't made any progress at all."

Yuu Tenkuji: "..."

Why did you suddenly start being sarcastic and mean towards your sister?

Although it was strange, Yuu Tenkuji didn't intend to be curious about the sisters' story, so she shut her mouth as if she hadn't heard anything.

Yukinoshita, however, seemed to have been suddenly inspired to talk, and continued with great interest:

"Although she's still growing, she's so cute! Not just her looks, the way she stares at people is like a cat resting against a wall, making you want to keep playing with her~"

As she said this, Yang Nai slowed down the car, held the steering wheel with one hand, took out her phone with the other, quickly tapped the screen, and showed him a photo:

A beautiful girl with long black hair walked down the street, turned around with a cold expression, and looked back with an awkward dissatisfaction in her eyes, as if she wanted to glare through the person behind the camera.

"How about it? Isn't it tempting?" She looked at him expectantly.

"Aha……"

With a wry smile, Yuu Tenkuji turned her gaze away from the photo.

Not knowing if the question was a bait, he could only give a vague answer: "All I can say is that you two are both very good-looking... Also, please watch where you're going while driving."

Putting her phone away, Yukinoshita Haruno finally looked ahead and said with a grin:

"After all, we're biological sisters~ Although she can't compare to me no matter what, that's precisely why she has to work even harder, and that's more interesting than any TV show!"

"..."

How dark must this person's heart be to say that the younger sister's hard work is more interesting than TV programs?

Tenkuji Yu couldn't help but click his tongue in amazement, while Yukinoshita Haruno, as if she hadn't noticed his expression, continued to talk endlessly about her childhood stories.

She didn't touch on any private matters; she simply recounted Yukino Yukinoshita's history of failures in an intimate tone, sometimes laughing so hard she slapped the steering wheel, filling the car with cheerful laughter.

Yuu Tenkuji no longer knew whether she liked her sister or hated her to the core.

On one hand, when talking about Yukino Yukinoshita, Haruno Yukinoshita's face was full of natural smiles, her spirits were high, and she was gesturing wildly. Even the system kept popping up rewards of tens and hundreds of yen, clearly she was very happy from the bottom of her heart.

At that moment, Tenkuji Yu thought he had discovered someone even more of a siscon than himself.

On the other hand, she, like a magazine that constantly exposes scandals about female celebrities, went on to recount her sister's dark history and bluntly mocked her.

Even Yuu Tenkuji could hardly bear to listen to that sarcastic way of speaking.

"Not one of our kind, but a twisted fan..."

After comparing himself to his past self, he couldn't help but sigh.

Following "a woman with a terrible personality and pitiful appearance," Yukinoshita Haruno in his mind has gained another label.

—A twisted sister complex.

Time passed by unnoticed, and the scenery outside the window rushed past, as if we had already exited the interchange and arrived in the next city.

"Phew... This is the first time I've shared Yukino's story with someone so readily."

Finally, as if she had finished talking, Yukino Shino pursed her lips and sighed contentedly.

A cheerful, relaxed smile played on her lips. She brushed her shoulder-length black hair behind her fair ears, glanced sideways at Tenkuji Yu in the passenger seat, and teased her:

"It's a pity you're just a borrowed boyfriend. Otherwise, if I introduced Yuuyu to Yukino, I'm sure I'd see a very interesting expression on her face, right?"

The idea of ​​a classmate becoming her older sister's boyfriend is something that would definitely make Yukino lose her composure.

If she already knew Yuu Tenkuji and their relationship was even quite good, then just thinking about it made Yukino Yukino almost act impulsively.

Of course, it can only be a thought at most.

Teasing her younger sister was just a hobby for her, and renting a boyfriend was something that would affect her reputation, so she couldn't tell Yukino or her other family members under any circumstances.

Compared to her numerous concerns, Tenkuji Yu felt nothing but relief:

"That's right, luckily I was just borrowed."

He would absolutely refuse to be called "brother-in-law" by classmates.

Yuu Tenkuji didn't intend to ask why she suddenly changed the subject to her sister. After seeing that she had reached a certain point and given her a reward of nearly 10,000 yen, he asked a question he had wanted to ask from the very beginning:

"Miss Yang, where are we going this time? The sports center? Or..."

"Yes, it's the sports center."

The adult woman, dressed in a sexy suit and pressing the accelerator in high heels, nodded in affirmation.

Chapter Twenty: Are you confident in your skills?

Not long after, the black luxury sedan drove into the underground parking lot of the "Aomori Sports Center".

"It really is a sports center... But why did you specifically come to the city next door?" Yuuki asked, puzzled, after glancing at Yukinoshita Haruno skillfully reversing into a parking space.

"Aren't there a few stores in the city center? Why go this far?"

"Just to be safe," she replied casually. "Those sports centers all have business dealings with our family, so it's easy to run into acquaintances. It wouldn't be good if they reported us."

He was taken aback: "Is your family that strict?"

"It's a special time, you know." Yukino Yukinoshita shrugged, offering no explanation, and unbuckled her seatbelt as soon as the car was parked.

Yuu Tenkuji also acted as if he hadn't asked.

The affairs of the powerful families were none of his concern; he was merely a ruthless miner.

As for Yukino Yukinoshita, she simply wanted to find a playmate... or rather, a toy, to accompany her through this period when she could still "freely date," so of course she would try to avoid letting him into her life.

A relationship built on lies requires maintaining distance from each other's truths—this is a consensus they both share.

If I weren't classmates with Yukino Yukinoshita, she probably wouldn't have brought up the topic of her younger sister.

"Get off the bus, I need to go to the restroom to change my clothes."

Opening the car trunk, Yukino took out a luggage bag. After Tenkuji Yu got out of the car and closed the door, she locked the car with two beeps, then turned and walked away.

Tenkuji Yu followed behind her, and the two took the elevator to the first floor, where they parted ways in front of the restroom.

After washing his face and making sure he was no longer the disheveled, sweat-soaked man he had been a while ago, Yuu Tenkuji left the men's restroom and planned to sit and wait for her in the rest area outside.

There was also a man on the bench, presumably waiting for his girlfriend. He would occasionally glance in the direction of the women's restroom, and when he saw Tenkuji Yu walking over, he smiled and nodded at him.

He nodded in response, sat down, and started scrolling through his phone; neither of them intended to speak to the other.

While aimlessly scrolling through photos of pretty girls on Twitter, Yuu Tenkuji experienced for the first time the feeling of a boyfriend waiting for his girlfriend to go to the bathroom, change clothes, touch up her makeup, and so on, scrolling through his phone wondering how long he would have to wait.

Perhaps once you get used to it, you'll be like the guy next to me, prepared for a long-term battle, and therefore won't feel anxious at all?

"Sorry to keep you waiting~"

About ten minutes later, the black-haired beauty came out of the women's restroom.

Her smooth, flowing medium-length hair was tied into a single ponytail, and her clean, crisp white sportswear accentuated her curvaceous figure. Her skin was as white and flawless as milk, with a healthy, rosy glow.

With a bright and cheerful smile, she was like the rising sun peeking out from the edge of the night, illuminating every place she passed through.

"This is so much more comfortable; this suit makes it hard to breathe!"

Yukino Yukino tugged at her collar, revealing her beautiful, slender, and alluring collarbone.

Yuu Tenkuji stood up, ignoring the envious look from her older brother beside her, glanced down at the bag of luggage in her hand, and then casually turned her head away:

"Now that you've changed your clothes, let's go."

"Okay, I'll lead the way~" Yukinoshita Haruno smiled cutely, walked over in her brand-name sneakers, and handed him her luggage bag.

Then, as if she hadn't done anything, she walked up to him easily and cheerfully, and said:
