What should I do?

Two sides of the same coin. 

Even though Isao might become a bad person tonight, as long as he didn't forget his original intention, he believed that everything would be okay. 

Yet, at the same time, while his instinct told him that something might happen tonight, he shouldn't jump to a conclusion. 

More importantly, who could stop him in this world? 

As he gained Tatsuya's DNA, he became the strongest in the world. 

Or rather, he was above Tatsuya since, unlike Tatsuya, who was just a boy, Isao's body had been enhanced by a blessing from a goddess and various DNAs he gained from all the creatures he had met during his adventures in various worlds. 

Frankly, if there was a reason why Miya seemed to be proactive about him, he could only say that it was all because of Miya's ability as a magician, which made her able to have the insight to judge people whether they would harm or be trusted. 

As Isao had gained Miya's DNA, he also got this ability, and what made him relieved was that he knew that Miya, Miyuki, Honami, and Tatsuya wouldn't do something harmful to him, such as catching him in a laboratory. 

Still, as he made his dinner, somehow, Miyuki asked, "Is there a point to cook by yourselves?" 

"Miyuki..." Tatsuya looked at his little sister, wondering why she was so rude. 

"It's fine, Tatsuya." 

Hearing Isao's answer, Tatsuya sighed in relief, but then being called Tatsuya was better than being called "boy," he thought. 

"Is it so weird of me to cook something?" Still, Isao couldn't help but ask. 

"It is." Miyuki nodded. "We have a robot that can help with household problems, right? Why don't you just use that?" 

As it was in 2092. Naturally, the development of technology was more advanced, and from those four DNA, Isao also understood that there were machines used to help with household problems. 

'Now, I understand why there are only a few of them.' 

Isao thought that there was something weird since even though Miya appeared like a wealthy lady, the people she brought with her were limited as it only consisted of her two children and single bodyguard, but then he also understood that whether it was their food, cleaning, and many others were taken care of by machine, which was more convenient, efficient, and cheap. 

So, there was no doubt that his act of cooking by himself made all of them feel weird. 

"You can say that it is my hobby," Isao said. 

"Hobby?" Miyuki felt weird. 

"Also, it seems that you think my food tastes worse than something made by a machine." Isao felt that he was being challenged by this little girl. "Let me show you what real cooking is." 

"...." 2x

Why did it feel like they saw him blazing in the fiery fire? 

Still, Miyuki didn't hate Isao's presence since, with Isao, her mother told her to call Tatsuya "Onii-sama," and Tatsuya could call Miya "mother" and her "Miyuki." 

This was something that she had never imagined before. 

While Miyuki felt sorry for her real father, she felt like Isao; they were like a real family. 

Yet, this couldn't be helped, especially when her father was in a lower position, someone invited her to become a son-in-law, and more importantly, he was using her mother's mother all the time for various reasons, which made her speechless and wondered where his dignity was. 

"What are you going to cook?" 

Miya also stood near the kitchen and asked curiously. Like her children, it might have been her first time having a meal prepared like this after she had lost her parents and sister. 

"You haven't tried an Okinawa dish, right? I will cook it for all of you." 

"...so you really come from Okinawa?" Tatsuya asked with a doubt. 

"Why? Did you doubt me?" 

"For Okinawa people, your skin is too light." 

As Okinawa was closer to the equator, the sun was particularly intense. There were two seasons instead of four in this location, so it was normal for one to have a darker skin color. 

Yet, Tatsuya couldn't see such a skin on Isao's. 

Or rather, Isao's skin was so much better than anyone's that it made Miya and Honami feel slightly jealous. 

"Did you use skin care or something?" Honami asked curiously. 

"It's all natural."

After all, all the worlds that he had ever entered were worlds in the past or zombie-filled worlds. In such worlds, how could he care about skincare?

Somehow, those words brought resentment from Miya and Honami. 

Still, they were soon attracted to his cooking skills, from how he wielded a cooking knife and all other actions, including the scent of the food. 

When the smell of food spread inside the room, they felt their stomachs rumbling. 

Tatsuya looked at his stomach weirdly, but he didn't say anything and kept staring at Isao, who seemed to taste the food in satisfaction. 

"Is it delicious?" Miya asked curiously. 

"Do you want to try it?" Isao took a spoon for Miya to taste, and somehow, he tried to feed on her.

"...." Tatsuya, Miyuki, and Honami. 

No one thought that Isao had put poison on the foods, especially when all of them watched the process; he also had tasted the food by himself, and how Tatsuya had used the "Elemental Sight" on the foods from time to time, but then again, wasn't this guy so brave, trying to feed Miya? 

After all, Miya always appeared stern and strict, so wouldn't she be angry when Isao tried to tease her like this? 

Only Miya lightly pulled her finger behind her ear softly, opened her wet and moist lips, sticking out her tongue to touch the food from his spoon before she let him feed on her. 

"Hn~! Delicious~!" 

Miya was surprised as she covered her lips with her hand, showing the modesty of a woman. Yet, the taste of the food was more special than she had thought, especially when it warmed up her entire body. 

"Is it really so delicious, Okaa-sama?" Miyuki asked with doubt since her mother's reaction seemed to be exaggerated. 

Tatsuya and Honami also wondered whether the food was really that delicious, as it was their first time to see such an expression from Miya. 

"Yes." Miya nodded, and at the same time, it was her imagination, but her body felt better somehow.

On the other hand, Isao was silent for a while before he threw the thought away. Still, watching the three, who were more cornered about the food instead of what he did with Miya, he sighed helplessly. 

Yet, he also knew that due to many things that happened in the past century, the matter of sexuality wasn't as open as before.

Moreover, due to the little Ice Age that happened in the past, everyone's clothes had become more reserved, and most of their bodies were hidden. 

Still, even if Miya appeared reserved with her luxurious dress, the shape of her mature, luscious body made it impossible for him not to have a strange thought on his mind. 

"By the way, you three, help me to bring the plates." 

"O-Okay." 3x

The three quickly helped him, and then soon, the dinner was ready and served on the table. 

Unlike with the robot, the dinner took quite a while to prepare, but when they tasted the food, their eyes shone, and somehow, they forgot their manner. 

"Miyuki, Tatsuya, where is your manner?" 

Still, Miya didn't forget the two and lightly chid her children. 

Hearing their mother's words, Miyuki and Tatsuya quickly slowed down and ate the food slowly. 

"Listen to your mother. There are still a lot of them, and no one will rob your food," Isao said, looking at the two. 

"Um." 2x

Only Honami felt strange, wondering why Isao was like the father of the two. 

Well, Isao had experience as a father or a stepfather, so it was easy for him to take care of Tatsuya and Miyuki. 

Nevertheless, the dinner seemed to be more festive, and the dry atmosphere that existed on this trip somehow disappeared when Isao was there. 

At the same time, while Tatsuya felt that it was subtle, he could feel that his body felt better after he ate Isao's food. He could even see his mother had a good appetite, even though she rarely ate anything due to her weak constitution after constantly using her magic. 

Yet, after tasting this food, somehow, they felt reluctant when they thought they would be separated from him after they left Okinawa. 

Still, Isao would be with them during their stay in Okinawa, so Tatsuya wished to talk with him more about martial arts and many other things. 

"Tatsuya, Miyuki, you two go to sleep soon. Tomorrow, you can ask him for training in the morning," Miya said strictly. 

While the two felt reluctant, they could only follow Miya's words. When they left, Miya said, "Honami-san, please lead Iinuma-san to his room." 

"...I am really going to stay?" Isao looked at Miya strangely. 

"Yes." Miya nodded. "I have said it before, right?" 

Isao thought for a while, but since he didn't have a place to stay, he decided to agree. 

"Then, Iinuma-kun, please follow me," Honami said with a gentle smile, leading him to his room. 

"Okay." 

"By the way, did you learn martial arts from childhood, Iinuma-kun?" 

Still, as they walked to his room, Honami asked him various questions. 

"Hmm... I am not." 

"Huh? Really?" 

"Yes." Isao nodded. "I didn't learn any martial arts until a few years ago." He didn't lie since he only learned his martial arts after he visited the "Kimetsu no Yaiba." Before that, he had never learned anything and only focused on improving his physical ability and health. 

"But you are so strong!" 

Honami thought that Isao learned his skill from childhood and became a master, but it seemed that wasn't the case. 

"Just say that I am more talented than others." 

"...I have never expected that you are so narcissistic, Iinuma-san." 

"That's the fact, though." 

The two smiled, then chuckled. 

Facing Honami, even though she appeared gentle and kind, Isao knew that she also had many worries, but then again, they had only met in a few hours, and he knew that it would be too much of him to ask about her life, so his motto during his stay in this villa was to never ask anything. 

Isao only wanted to learn about this world slowly, steadily, and peacefully, but then again, he felt that it might be a little hard after he got involved with Tatsuya. 

Still, he didn't hate Tatsuya, so it didn't matter. 

Moreover, as he had decided to take this job, he wouldn't quit halfway as it didn't fit with his personality, who tried to become a good person. 

"This is your room, Iinuma-san. If you need anything, please tell me." 

"Thank you, Sakurai-san." 

"Yes." 

After Isao entered the room, Honami took a deep breath, trying to calm her beating heart. She knew that it was impossible and there was no possibility between them, especially due to her identity, yet she couldn't help but feel at a loss before shaking her head, wondering why they had to meet when nothing would happen between them. 

As she let out a helpless sigh, Isao was in his room, taking a bath and thinking about what he should do in this world. At the same time, he wondered whether he should go back, as this world was as good as his when he got Tatsuya's DNA. 

But then, again, it would be a shame if he just went back so soon, especially when he knew that he had to face many things in the world of "Danmachi." 

Isao wanted to relax for a bit. 

Still, as he thought so, he sat on the sofa inside his room, watching the beach at night, enjoying his time. Yet, it was hard, especially when he thought of Miya's figure, who kept resurfacing in his mind. 

'Let's go back.' 

In the world of "Danmachi," he was still in Demeter's room so he could ask for Demeter's comfort, then went back after he had calmed himself. 

Only—

Knock! Knock! Knock!

"Yes?" 

The door was gently opened, and the figure of a woman he had always dreamed of after he came to this world appeared before him. 

"Sorry for bothering you, Iinuma-san, but do you mind if we talk?" 

"...sure." 

Miya smiled, then closed the door. 

However, Honami, who was outside of Isao's room, was in a dilemma and panicked as she wondered what she should do.
