The library is a place for study

As if it were a dream, the excitement that came from the Sunrise Festival disappeared, and what was left was the tension that came before the mid-term exam. 

The prefectural or national competition might be important, but if they couldn't even pass their mid-term exam, then one could only give up their club activity. 

However, such a problem didn't exist in Mizuto. Instead, he was relatively calm and even anticipated this exam, especially with the bet that Yume had set during the Sunrise Festival. 

'Onii-chan...' 

The thought of Yume calling him "Onii-chan" with such a coy and meek voice for a month made him study harder. 

The sight of him also made Yume desperate, especially when she saw how serious Mizuto was. 

When Mizuto didn't study seriously, he was already awesome, but what if he put more effort into his study? 

Yume could imagine that she would be defeated mercilessly by Mizuto without being able to fight back at all, and her fate, being his little sister, had already become an indisputable fact! 

However, as an older sister, Yume still had pride that she couldn't throw. It was impossible for her to give up, so she also studied hard. Moreover, during the night, her effort to stamp the image of their older sister in his mind became stronger, and they often performed many perverted acts with her as his older sister. 

The most perverted one that they had done was at how Mizuto would lay on her smooth thighs while sucking her tits while Yume would stroke his penis affectionately. 

This might be a humiliating position for Mizuto, but he enjoyed it, and some spices made their relationship interesting, so he just let her go, especially since he would be the one who humiliated her after the mid-term exam. 

Yume could see that, so she also strengthened her effort by trying to dote on him so he would give her mercy and not be so cruel to her when she became his little sister. Still, frankly, being a little sister to him definitely wasn't bad, but somehow... if she didn't fight, then she would have nothing, so she had to do her everything to fight! 

The pervertedness of Mizuto and Yume might be subtle, but Akatsuki and Reina could see that, and they also doubled their efforts to take down Mizuto. 

Whether it was a threesome, wearing a uniform, or giving him a double blowjob. 

Even though Yume had drained him every night, Mizuto would wake up again and again with a better fighting spirit, like a phoenix that was reborn from the ashes.

Watching how Mizuto became even stronger, the three had to admit that they were helpless. 

Even worse, Akatsuki and Reina knew that they weren't the only ones, and Mizuto also made a move with many other women, yet they saw him always lively, showing an amazing power that could only make them look up and fascinate them. 

This time, while it was rare, Mizuto decided to study alone in the library. His women also didn't bother him, especially when they knew he wanted to study. Moreover, if they were with him, they were afraid that they might wake up his beastly side, which made him unable to focus on his studies. They loved to be with him, but they wanted to support him more. 

Yume was even more so, even if she knew that this might cause his grade to be better, and losing the bet, she could only accept everything. In the worst case, she could only act like a loving little sister and acted like a spoiled little baby later. 

'Well, being a little sister occasionally isn't bad.' 

Yume somehow accepted the fact that she would lose, but it didn't mean she had given up!

Fight, Yume! 

Mizuto didn't know what Yume thought, and he just studied quietly while doing his business alone in the library. Anyway, the news of him having a girlfriend spread to the entire school and the nearby schools. While the number of love letters on his shoe locket never decreased, and the numbers even increased, making him speechless. 

Yet, a human had always loved a challenge. 

Knowing that he had a girlfriend, instead of moving away, they tried even harder as they wished to take him away from his girlfriend. 

As for Miyako Shikimori, who was rejected, they only thought of her as a fallen warrior, but they were different! They hadn't been rejected yet, and they were going to fight for him! 

Mizuto didn't know something incredible was happening, and he just quietly spent his time in the library after school. 

"What book are you looking for, Irido-kun?" 

Mizuto, who was browsing over the bookcase to search for a book that might catch his interest, turned and saw Ai Kamiya was there. He thought that she would leave him after she saw his close relationship with Reina, but the next day, when he came to the library, she acted as if nothing had happened. While he was surprised, if she didn't say anything, then he wouldn't say anything. 

The two spent their time as usual. 

While she did her job as a librarian, Mizuto casually looked around the book, and during this moment, she would come to him and talk to him occasionally. 

"I am looking for a history of Ken Arok." 

"Ken Arok?" Kamiya was curious. "Who is that?" 

"He is the first king of Singhasari, one of the most powerful kingdoms in Southeast Asia, and also a powerful king that is capable of defeating the Mongol Empire." 

"Huh? Really?" While Kamiya didn't know Singhasari or Ken Arok, she knew about the Mongol Empire and its horror. The fact that Japan was able to defeat the Mongol Empire due to the luck known as "Kamikaze" or "Divine Wind" was a well-known fact. 

If there had been no such wind, Japan might have already been invaded by the Mongol Empire, so when she heard a kingdom in Southeast Asia was capable of defeating the strongest empire at the time, she was surprised. 

However, Mizuto didn't care much about this feat, and what made him interested the most was how Ken Arok got to know his wife, Ken Dedes, by watching how he caught the sight of her naked legs and thighs, and he saw that her genitals were "shining."

Frankly, this made him speechless, not only because the people of the past didn't wear underwear but because their pussy could shine. 

However, Mizuto didn't feel that this was nonsense. The love juice that was secreted from a pussy had always appeared translucent, and when there was a light, it would gleam, so wasn't it natural for her pussy to shine, especially when this incident happened during the day. 

Mizuto had to say the people of the past loved to exaggerate something, but the thought of such history also made him think that Kamiya's lips shone under the light that passed through the window of the library. 

She basked in the light; her sweet cherry lips appeared so delicious that one was tempted to take a bite. 

"So, even if his wife at that time had a husband, he still tried to seduce her?" Kamiya was dumbfounded, and a strange emotion was born when she heard the story of Ken Arok and Ken Dedes. 

"Yes." 

"Why so? Isn't that unethical?" 

"Haven't you heard a saying?" 

"What do you mean?" 

"All fair on war and love. Moreover, an emotion always appears unexpectedly. You might be able to control it, but it is impossible to erase it completely." 

"Are you the same?" 

"I do." Mizuto nodded as he looked at Kamiya softly, yet from his eyes, Kamiya could feel a blazing inferno-like desire. 

Kamiya blushed and felt her body was hot. She felt shy, but she didn't run away. The thought of him having such a thought made her happy. Even if he had a girlfriend, she couldn't give him up, and having a small conversation with him always made her happy. Even if there was no result between them, she was fine with it, but now, everything has changed. 

An emotion has always existed within a human. 

While it is possible to control, it is impossible for one to be able to dominate it and take full control over it. 

Mizuto definitely wasn't someone capable of doing such a thing, especially when Kamiya was around. Still, while he held on, she apparently couldn't. 

Kamiya was shy, yet her impulse couldn't be stopped. 

She might regret this, but she just wanted to try it even if nothing would happen between the two. 

"Kamiya?" 

Watching Kamiya, who approached him as if she couldn't control her emotions, Mizuto sighed and thought that he might need to teach her that there was someone one couldn't provoke. 

So, as Kamiya moved closer, Mizuto also did the same and took her first kiss.
