Mammoth's Tusk

On the next day, whether it was Nami, Reina, or Akatsuki, they were dumbfounded when they saw the clubroom of the "History Research Club" had changed. It was no longer as empty as before. Instead, it was full of many things, and it clearly fit the elegance and scholarlyness of the room of someone who had learned about history. 

Inside this room, there was a sofa, several chairs, tables, a bookcase with a variety of books, and many other items that gave off a vibe of something that usually appeared in the history room, such as a fossil. 

"...is this an elephant's tusk?" Nami asked with a doubt. 

"...he told me that it was just Mammoth's tusk,"

"Ma-Mammoth? Is that a Mammoth?" Nami was dumbfounded.

"Yeah." Akatsuki nodded. "He told me that it was a replica..." Nevertheless, she didn't think this Mammoth's tusk was a replica. Instead, there was a high chance that it was real. 

"....." Nami. 

Akatsuki wasn't surprised by Nami's silence since she was also in shock as she looked at the Mammoth's tusk displayed on the wall. She could tell that Mizuto was a bit excited, as he had bought the tusk of Mammoth, but she had to say her man really loved to have fun as he had turned this place into a secret base, something that every child longed for. 

However, with his wealth, was there anyone who could stop him?

Being backed up by one of the largest conglomerates in the world, Akatsuki realized the power that was held by her man for the first time. 

"...." 

Nevertheless, Nami was unable to say anything. She knew that this guy was working, but she didn't know the details, yet when she saw everything in this room, she could tell that his job was pretty lucrative. 

Or rather, this guy must be rich! 

Compared to her house, all the wealth gained from her divorce, savings, and also salary as a teacher, Nami knew that all of them were nothing to Mizuto, which made her helpless since her plan to make him a household husband had failed. 

At that moment, Nami knew that her role could only become his mistress, yet somehow, she didn't really hate it. 

Reina didn't say anything and touched the tusk of Mammoth, blushing as it reminded her of something. 

"....." Nami and Akatsuki. 

The two looked at Reina for a while before approaching this tusk of Mammoth and rubbed it with their hands curiously, feeling the hardness of this furry gigantic elephant that lived 4,000 years ago. 

Unlike Mizuto, who had no intention of coming to the clubroom during the school break, the three couldn't wait any longer and went when he told them that his people had finished the decoration. When they saw it with their own eyes, they had to say... this was incredible. 

They weren't sure how many times they had been amazed, but there was no doubt his taste in furniture, decoration, and design was as amazing as ever, especially the Mammoth's tusk. 

"... has he told you what his job is?" Nami asked for the first time.

"Hmm..." Akatsuki thought for a while and said, "He is an associate of the Dipper Group. While there might be more about him, he is working as a researcher for the group's investments, especially in real estate, infrastructure, and food. There might be more, but I am not sure since he doesn't tell us much." 

Well, probably, it was also meaningless to tell her. 

Akatsuki didn't feel sad since this was a reality. Unlike him, who was exceptional and special, they were just a high school student and a high school teacher. 

"But I am sure he has an important position in this company since there are often men in black suits who come to follow and protect him. If I am not wrong, they should be his bodyguards." 

"Bo-Bodyguard?!" 

Not only Mizuto's work, Nami was dumbfounded by how he would be protected by a secret bodyguard. Then her expression was slightly pale since shouldn't they know that she had molested him too at that time? Yet, until now, no one had come to her, so she knew that everything was alright. 

Nevertheless, Nami had made up to become his mistress. 

Yet, Akatsuki, who watched Nami's reaction, nodded secretly since she had achieved the effect that she wished for. Unlike Reina, with whom she was familiar, she was unfamiliar with Nami. 

If there was a reason why she approached Nami on her initiative, it was because she wanted to protect Mizuto. 

Unlike Reina, who was simple and only used her crotch to think, Nami was an adult, and no one knew what this woman was thinking. 

If possible, Akatsuki wanted Nami to leave. 

While it was impossible, considering it was Mizuto's choice to hold Nami, Akatsuki felt... threatened somehow. She knew that she shouldn't think of this, but Mizuto didn't have a mother, and probably... he sought that mother figure from Nami. Moreover, while he might not realize it, she knew that he had a preference for a mature woman. 

If there was a reason why Mizuto never broke the family of others, it was because he was still kind. 

If Mizuto were a devil, he would probably destroy many families by taking the wife of that family, leading a married couple into divorce. 

Fortunately, Nami was a widow, so Mizuto hadn't walked into the path of no return. 

Yet, Akatsuki knew that if Mizuto wished to, he should be able to do it, but she didn't want that. Nevertheless, it didn't mean that it was entirely bad since she knew even if she grew older, she would still be attractive in his eyes. 

Rather, she was sure that Mizuto would be more excited for her. 

Instead of having a sexless life, she was sure that guy would become beastly, which somehow made her excited, thinking about their future. 

Yet, there was no doubt, if possible, that Akatsuki wished for Nami to leave. While the chance was almost zero, considering what kind of a woman wanted to leave such a charming beast, she still had to show how exceptional Mizuto was to Nami so Nami would feel inferior and never think of a relationship other than a lover with him. 

"By the way, is it me, or is this room a little smaller than before?" Reina suddenly said. 

"Huh? Really?" 

When they heard Reina's words, they looked around and thought that this room was a little smaller than before. While they felt confused, they recalled the design of the room, which Mizuto drew yesterday. 

"Shouldn't there be a secret room?" 

"...no way, right?" 

"No, if it's him, then it should be possible." 

"..." 

The three looked at each other before they looked at every corner of the clubroom after they locked the door and closed the curtain so no one could tell what they were searching for. 

"Ah, I found it!" 

Akatsuki found something strange in the historical book, so she touched it, and a hidden door was opened. 

"....." 3x

They fell in silence; then they entered the door before they saw a small room inside, hiding behind. If they had to say, it was like a room in the capsule room but with a higher ceiling. 

Watching this room, they blushed and understood what this room was intended for. 

It was also because of this, they had to say; he was as amazing as ever. 

"Do you think this room is soundproof?" 

Without further ado, they tried to see how well this small room could insulate their voices to the outside.
