I am that male friend in the harem story

Not only did he get a girlfriend, but Ishigami also raised his physical ability to level two. 

[Physical Level 2 (4/100).]

In the mirror, he could see his body become better. His body was no longer all bones, and while it wasn't conspicuous, it was easy to tell that he had the body of a manly man. 

'As expected, a thin body is easier to develop.' 

Unlike a fat body that had loose skin, which made it harder to develop, the thin body was easy to develop since as long as he trained a little harder, the muscles on his body quickly formed and turned him into a healthy young man, who was favored by many older ladies. 

Still, he had to say that being a young man was hard, especially when he was so healthy. 

As a young man, his body was jumpy, and it felt like he couldn't stay calm, especially when he looked at a woman. Maybe this didn't happen at all since some people had low sexual needs, but his needs in that area were probably strong, and as his physical ability improved, he was in a mess. 

Even worse, there were many charming women around his side, and while he didn't want to think something rude about them, when he thought about how soft Chika was, how bold Kaguya was, how gentle Tsubame was, and how obscene the kiss he shared with Onodera... he let out a helpless sigh, staring at his raging erection. 

Wet dreams aside, he really didn't want to wank himself, so he could only wait for Onodera to open up to him. 

'Wait! Wait!' 

He rubbed his temple, trying to calm himself, feeling helpless by how energetic his body was. Usually, a protagonist should be cool, able to control themselves, and all calm, yet why was he just so horny? 

'I'm like a monkey in the heat.' 

It wasn't that he couldn't control himself, especially when he could work out or study, but... when he neither did that, it was just... so fucking damn hard. 

Rubbing his face with cold water, he hoped that everything was solved, but—

"Yuu! How long are you going to be in the bathroom? You are going to be late—"

"...." 

It seemed he knew a way to calm himself.

Ishigami definitely didn't do anything weird; instead, he was calm the moment his mother saw him as he was embarrassed, feeling ashamed, thinking his naked body was seen. While there might be a memory of him bathing with his mother during childhood, it was a time when he didn't know the difference between a man and a woman. 

Yet, he still knew what to do and wouldn't do, so he hurriedly left, thinking it was horrible to be young since his head had always been filled with messy things. 

Excess energy made his head often hallucinate, and it was even worse when he just kept everything inside. 

Pressing his head against the door of the train, he closed his eyes, trying to calm down, and at the same time, trying to chant a sutra, thinking that it could calm him down. Still, as he did so, he couldn't help but hear the conversation of a few girls on the side. 

"Hey, isn't he kind of cute?" 

"Ah, now you mention it." 

"From the uniform, he seems to be from the Shuchi'in Academy." 

"Do you want to talk with him?" 

"Eh? But if I am rejected, then won't it be hard for me to enter the train?" 

"....." 

Ishigami fell in silence, realizing that he had become popular. This was weird, he thought, considering how low the opinion of others toward him was, and it might be his first time to be treated this way, but then again, he had cut his hair, and his body had also improved. More importantly, the way he carried himself was different. 

Unlike the previous Ishigami, who had always hung his head low and had his face mostly covered by hair, he stood tall, his back was straight, and the muscles on his body made him appear more manly. 

If there was a little trouble, it would be the fact that he might need to change his uniform in the future. 

Not due to the bulky muscles like a Terminator, but due to his height increase. 

Regardless, he turned and met the gazes of the girls who talked to him, and from their uniforms, he could tell that they were from another school nearby. Like any guy in high school, the girls were also quite pervy as they also wished to have a romance like in the shoujo manga, waiting for their prince in white horse to come to them. 

Or a domineering CEO to come and dominate them. 

Unfortunately, those girls wouldn't meet such a prince in high school as most high school students were rarely able to talk to a female maturely and calmly. While not all, most of them would be jumpy, thinking whether that female liked them, turning away, blushing, and feeling embarrassed, but this was normal as they were in the process of learning. 

Still, it was clear that the girls were also embarrassed since Ishigami noticed them, but facing them, he smiled softly, telling them there was no harm, which caused them to be shy but also gave them the courage to approach him. 

"Um... if you don't mind, can we get to know each other?" 

"......" 

Ishigami never thought that they would really approach him.

"I am sorry. I have a girlfriend." 

Ishigami decided to say so since he noticed the same students inside the car. He had just made a girlfriend yesterday; if someone suddenly said that he tried to get to know cute girls from another school, what would happen? 

He was afraid that tonight, he would be thrown into Tokyo Bay while being stuck in a cemented barrel. 

Not only due to Onodera but because of Kaguya. 

Frankly, he wanted to be low-key first; at least, he hoped that on this weekend date, the love between Kaguya and Shirogane could bloom so that Kaguya would lose her interest in him and give all of her love and attention to Shirogane. 

More importantly, with Kaguya's excessive nature, especially after yesterday, he didn't want to test her nature. It wasn't that he thought she would monitor him, but in this era of information, it was easy to get, especially through social media; many things could happen, especially when many people had a lot of free time in their lives. 

If there was something fortunate, it was the fact that when someone took a picture or video with their phone in this country, it was impossible for them to hide the sound and would quickly be noticed, so he knew that he was fine. 

Still, he might be thinking too much, but should he also start to learn martial arts? 

If he remembered well, there was a Muay Thai lesson in the gym, and it wouldn't hurt to learn it. 

But then again, in the modern world, having money and a weapon should be more useful, he thought, as people would cower in fear when they saw someone holding a knife or a gun, or people would become obedient dogs as long as it was for money. 

Ishigami had just gotten a girlfriend, so why should he do something strange?

Moreover, he wasn't someone who would hurt his girlfriend or the people who had cared for him just to get to know a few cute girls who weren't even the parts of heroines in the story. 

Still, if those cute girls didn't study nearby, then his answer might be different, he thought.

Regardless, he should remember more sutra so it could help him to throw away all of his worldly desires, helping him to calm down from the heat that came from his body. At the same time, knowing that he had only ten years in this world, he needed to learn as much as possible before he went to another world so that way, in case he was transferred into an unfavorable character, he didn't give up and didn't have to do something that would hurt those who cared about him. 

As he thought so, he entered the school and saw Iino, who was full of sweat, walking somewhere as she dragged something heavy in a certain direction. Letting out a helpless sigh, he walked toward her, wondering how someone could be so stubborn as a mule.

Sometimes, I just write whatever I think of, so be patient, okay? 

By the way, just in case he goes to another world, which worlds do you want him to be in? 

Yosuga no Sora? 

Yahari Ore no Seishun?

Kiss x Sis? 

Keikenzumi na Kimi to, Keiken Zero na Ore ga, Otsukiai suru Hanashi?

Uzaki-chan? 

Rental Kanojo? 

Well, you can write what you think is good here.
