As the two hugged each other, Martha showed a soft smile, but Sayuri showed a jealous expression. 

Nevertheless, it was good that Eriri got a good boyfriend, or else they knew that with her not-so-smart head, they were afraid that their family's wealth would disappear within her generation. 

As for the fact that Masa might steal their family's wealth, it was impossible since his wealth was about to reach the same level or above them. 

More importantly, they had known him from childhood and his loyalty since even if many tried to seduce him, he was still loyal. 

"You left me for so long..." 

"I am sorry. I am here now, right?"

"Um..." 

Hearing her voice mixed with loneliness and sadness, Masa was also helpless since, during spring break, he took the chance to take a business trip to Seoul, Shanghai, Singapore, and Indonesia directly, and naturally, he left his girlfriend.

"Oh, right, I brought souvenirs." 

Still, Eriri didn't have much interest in the souvenirs since there was something that she wanted to do with her boyfriend, especially when she felt something hard and big on her belly. Naturally, due to this, she clung to him even tighter since she didn't want her mother to see his growth. 

Her mother was a widow, and it must have been so long that she had been touched; then, all of a sudden, a strong and handsome young man appeared on her lonely days; by then, what would happen? 

"....." 

Still, her face flushed red somehow until Martha's voice suddenly interrupted her thoughts. 

"Leave the rest to me, Masa-sama. You should take care of Eriri-ojousama first." 

"Thank you, Martha-san." Hugging Eriri in his arms, Masa then said goodbye to the two. "Then, Sayuri-san, Martha-san, we will leave first." 

The two didn't stop Masa and Eriri, who went to Eriri's room, but Sayuri looked at the two for a while and said with a hint of jealousy, "They must be having sex now." 

"Madam..." 

"Well, I don't mind if she gets pregnant, but her fetish is quite worrying..." 

Placing her palm against her cheek, Sayuri was worried about her daughter. "Why is my daughter so useless...?" Yes, while her daughter was so lucky that she didn't meet a scumbag, somehow, probably Eriri's inherited the useless DNA of her father that she became like this, which made her, as a mother, wonder what she should do. 

"..." 

What could Martha do? 

Sighing, Martha let out a helpless sigh as she thought about her young lady's strange fetish.

"As expected, oyakodon is the only way to stop this." 

"....." 

What could Martha say? 

Both daughter and mother were the same, Martha thought. 

Still, as the two thoughts, the moment Masa and Eriri entered the room, they were no longer holding back, and the two quickly tried to fill up all the loneliness they felt after their parting. 

Her sweet cry echoed inside her room, and her body moved violently due to the delight given by her boyfriend, which made her love him deeply to the point of morbid obsession. 

"Masa~! Masa~! Masa~!" 

Then, all of a sudden, her body jolted intensely before she lay weakly as her body became all sensitive.

Eriri was only at her limit, but as expected, while Masa could do more with Eriri's body, her body couldn't do so.

It was even worse when his body grew stronger after his physical ability grew stronger due to another Masa.

Still, while Eriri wanted to do more, especially when she saw her boyfriend's state, she was too exhausted and sleepy, especially when she hadn't fallen asleep and was too excited, waiting for him to go back like a puppy. 

"Go and sleep." 

"But..." 

Eriri looked at Masa's stiffness and felt worried, but his gentle touch comforted her. 

"I am also tired since I just arrived at midnight yesterday. Let's sleep together." 

"Um..." 

Yet, even so, Eriri was worried since she couldn't satisfy her boyfriend, but as she was exhausted, she slept soundly in his arms, feeling all of her worries disappear. 

Still watching her cute sleeping face and pure white frilly undergarments, Masa looked at his lower body with a sigh. 

Yes, similar to Masa of DxD and Masa of Mahouka, Masa in this world also decided to choose his childhood friend. Before he got this system, he knew that many fell for him, especially when he probably appeared the best in the ward, but then he knew that if he wanted to get a better future, he had to study hard to get into the best university, so how could he have time to do that? 

While his IQ was quite good, he knew that he couldn't rely on his older sister and his parents' insurance money. More importantly, as a man, he wanted to become the provider, someone who could protect and bring peace to his family so they did not need to worry about starvation, poverty, and other problems in the modern world. 

So, even if he knew the feelings of those girls, he knew his priority as a man; how could he prioritize the feelings of a woman when he knew that he couldn't take care of her? 

While it might be sad, he knew he had to harden his heart since his ambition couldn't be stopped with just a childish feeling known as love.

A man was all about an ambition to become the best among all men within our limited time in this world. 

This was a man's goal, he thought. 

Yes, it was cold, but the world wasn't fair since if he wanted to be successful, then he had to sacrifice something, whether it was love, time, or something else. 

However, after he gained this system, he knew that there was no hesitation in his heart, so he took Eriri as his girlfriend. 

Yes, he might have met many girls in the year after he got the "Voice of the Future," but in his eyes, they were far behind this girl who kept waiting for him, stupidly like a little puppy. 

So, even if he knew that she couldn't comfort him fully, he didn't mind since sex wasn't the priority within a relationship, and for him to choose her, it wasn't because of sex, but of her dedication and loyalty chose to wait for him, and by his side accompanied him. 

Kissing her smooth forehead softly, which made her smile, Masa smiled, then closed his eyes, sleeping by her side since he had to admit everything he had learned today had exhausted him. 

Still, when they fell asleep, someone looked at his sleeping face as she breathed heavily before she looked at the girl by his side, then shook her head and left helplessly. 

Masa opened his eyes lightly, feeling the helplessness of the strong since he knew that by becoming strong, there was hardly anything that could be hidden from him, including the feelings of those around him. 

Still, after the two of them woke up, they ate, filling their bellies, before Eriri started to draw once again. 

Yup, similar to the original, she was an illustrator and also a mangaka. Still, as the illustrations drawn by AI became popular, and many even loved it, she focused more on her manga, which she worked on with Masa, who made the story.

After all, while an AI could draw a lot of good illustrations, its ability to write a story was low as an AI wasn't a human, so its understanding of a feeling was almost as good as zero. 

Yes, Masa was also a mangaka, but he didn't draw; he just wrote the story for Eriri, who wanted to become a mangaka as it was her dream. 

Simple and pure. 

Masa felt like if Eriri met a certain scumbag, there was no doubt she would be cheated to death by being told to draw illustrators for free to make a game, and in the end, when she wanted to develop her skill by choosing a better project, it would appear as if she had betrayed that scumbag who paid her nothing and just used her ability and reputation to gain rapid success without doing anything. 

Fortunately, such a plot didn't happen in this story since she met Masa, but while his girlfriend was simple and pure, unfortunately, her fetish wasn't simple, pure, or even cute, and he had to stop her from having this fetish! 

So, taking a deep breath, he said, "By the way, Eriri, can I say something?" 

"What's wrong, Masa? What's with that strangely formal tone?" 

"As your boyfriend, I have one request." Masa looked at Eriri and said solemnly, "Can you not use me as a model to draw the guy who stole the girlfriends, wives, or partners of the others on your NTR doujinshi?!" 

Yes, his girlfriend seemed to wish to see him hold another woman.
