Hina slept soundly, like a log, completely exhausted, yet the satisfied expression on her face couldn't be hidden. Instead, it was just clear and impossible to hide.
As for the one who had done it to her, Nifuji, also had fallen asleep by her side, but in a few hours, he woke up, feeling full of energy.
Was this the effect of his previous reward?
"Amazing..."
Nifuji was glad that he had spent that 100 million yen. After all, in many cases, while having money might be good, there were still some things that one couldn't use money to buy, or as people chased money, too much, they forgot that there were many ways for one to get something without money.
Regardless, he wanted the money and the healthy body, and he achieved it.
As for his work, he could think of that later, as he decided to rest in the bathtub, feeling the warm water that seeped through his body, healing his body and soul.
"It would be great if I could take a trip and have an onsen."
Suddenly, he thought of Chika Suzugamori, who had taken him on a trip based on the random questionnaire. While it was unexpected, it was also kind of fun, as the surprise kept the thrill going, and it also helped him to relax.
Previously, he had decided not to do anything and stopped working seriously, trying to increase the future of the company, as he knew that no matter what he did, it would be meaningless, especially when he couldn't do what he wanted to, considering he had to answer the doubts of the shareholders.
While he wanted to improve the company, the rest just wanted to enjoy the dividends, looking only for the short term, when the truth was that the wealth he would generate in the future would be beyond anyone's imagination.
It was like the story of the grasshopper and the ants; while the grasshopper wanted to just to have fun, and enjoy, the ants worked diligently, then when the winter came, the ants enjoyed their hard work, and the grasshopper could only beg, and when its request wasn't accepted, it would curse, saying the ants were heartless even though what had happened to him was all due to its own laziness.
Fortunately, he gained the equity firm, which enabled him to spend his time on something else. As for his work in the toy department, even without that position, it didn't really matter, as he had gained something better.
So, what should he do?
"Let's think about it later."
His mind, body, and everything were melting in this warm water, and he just didn't want to think of anything except enjoying himself, but soon, his body quickly turned stiff, especially when he heard the click sound, and the door of the bathroom opened.
"Hina—"
He thought that it was Hina, thinking that she hadn't had enough, but unexpectedly, it was Rui.
"R-Rui-chan?!"
He was startled and was in a mess. In a normal situation, people would hide their sensitive parts, but he knew that no matter how he hid it, his beast would be impossible to hide, and more importantly, why the heck was Rui all naked?!
"Ah, um... I-I am sorry, Hirotaka-nii."
Rui quickly apologized, but her eyes quickly drew toward his nether region, which put her in a daze.
"It's okay."
Nifuji tried to calm himself forcefully. "But, you should go out since I am still taking a bath." While he didn't want to give up his position in the bathroom, as he wanted to rest, he knew that he was the older one, so he had to give up. Helpless? Yes, but Rui was his little sister-in-law, so he had to give—
"I-It's fine." Rui suddenly said. "You must be exhausted, right? It's okay if you want to rest more."
"Thank you."
Nifuji thought that Rui was an angel, as he had never expected that she wouldn't bother him, but this angelic nature was a little too much, he thought.
"D-Do you want me to help you relax? I can give you a little massage."
"...." Nifuji.
Part of him wanted to nod, but Rui was Hina's little sister.
Frankly, it didn't really matter as Rui was an adult, and from what they talked about before, she also got her car driving license, but even so, there was something that one should do and shouldn't do.
"I don't think that it is good."
Yup, he decided to refuse.
"Why?"
"...what do you mean by why?"
He thought that Rui would try to rethink, but unexpectedly, his refusal made her more stubborn.
"Do you think that I am not good?"
Rui pouted, clearly, feeling annoyed by his refusal.
"It's not about whether you are good or not, okay?"
Nifuji rolled his eyes and asked, "What will happen if Hin sees us?"
"She is sleeping."
"...let's say that she sees us, what will happen?"
"I will just say that I am helping you."
"....."
Nifuji decided that talking was meaningless; instead, he tried to gauge Rui's intention by observing her eyes. Yes, she might be an adult, but she was still younger than he was, so her experience was small compared to his. Then, as expected, when their eyes met, she looked away, as her face turned redder.
'What a naughty girl...'
He sighed inwardly, thinking that Rui must have played with fire, and like a moth that was attracted to a fire, then burnt by it, he felt that she was such someone.
Or rather, in the original story of Domestic Na Kanojo, where Rui originated from, her future was kind of iffy. She lost her loved one, even though she had given birth to the daughter of the protagonist, and that protagonist even married her older sister.
Yet despite all of that, Rui still smiled, thinking that everything was fine.
Still, Nifuji didn't know the story, but he understood that if he did nothing, Rui would likely make a mistake in the future.
Instead of making a mistake with others, wasn't it better to make a mistake with him?
After all, if she made a mistake, such as getting pregnant by an irresponsible man, at least Nifuji could take responsibility instead of running away without thinking of taking care of her.
So, as he made up his mind, he stood up, letting Rui see his bare body.
At that moment, Rui couldn't say anything; her eyes just stared at him with a mix of surprise and a hint of lust.
Like how a man felt horny when he saw a naked woman, Rui reacted the same way when she saw Nifuji's body.
"Then, can you help me to wash my body?"
Yup, let's just wash his body.
