I am that male friend in the harem story

Nimbling, caressing, tying, and sucking. 

Karen had never thought that she would become a dirty girl who was obsessed with kissing. 

If her partner was her boyfriend or husband, this might not be a problem, but this person was someone who had trusted her and helped her as an editor. 

More importantly, Ishigami had a girlfriend! 

Yet, even so, this kiss... she couldn't stop and wished to continue. 

Like how the ardent love that existed between Shirogane and Kaguya in her fiction, Karen could feel such a feeling between her and Ishigami even if she knew that this was wrong. 

Yet, that rush of adrenaline disappeared, and Karen quickly realized what kind of wrong actions she had done, especially when she just pressed forward to kiss him after she saw him look at her with such a gaze. 

Still, was he hugging her waist gently due to his real feelings, or was it due to an act? 

As Karen was afraid to know the truth, she just didn't want to let him go, facing him, but she knew that as they parted their lips and gazed at each other, she had to explain her sudden action. 

So—

"...if Kaguya-sama confessed, then I thought she would do that."

Karen decided to make a clumsy excuse. 

"....." Ishigami. 

Watching this expression of his, Karen wished to run away as far as possible! 

No, she should just book a ticket to Alaska and run away! 

Still, when Karen thought to apologize, she ran away. The arms that hugged her waist tightened as she moved closer to his chest. 

"Sorry, it's my fault." 

"...why did you apologize, Ishigami-kun?" Karen looked at him in a confused and slightly agitated voice. 

"You are not as dull as others, and I am sure that you have realized that I didn't hate your advance and just let myself be kissed by you. I should have been able to push you and stop this before all of this happened, but I let my desire take control over me."

"No! If someone was at fault, then it was me who couldn't control myself..." Karen clung to him tightly as she buried her face on his strong shoulder. "I shouldn't have said anything to you at that time..." 

If they remained strangers without knowing each other after Ishigami took her manga, and she hadn't taken the initiative to ask him to become her editor, would all of this have happened?

As the two were together, their feelings grew slowly stronger, and in the end, something like that happened. 

"Really? I am glad that you asked me at that time." 

"...you don't appear as docile as you appear to be, Ishigami-kun." 

Karen looked up at him, staring at his gentle and calm expression. Her eyes were still red, yet her body was less tense and appeared relaxed. 

"I am not." 

"I can see that." Karen leaned on him in her most comfortable position and said, "I can tell that you must cheat on your girlfriend, a lot of them." 

"...." 

Did she really know it? 

Or did she just make a guess? 

It was just when Karen leaned on him, her eyes looking down, that she realized the stiffness that Ishigami had tried hard to hide. 

"...did you get hard?" 

"...sorry." 

"I-It's fine. I-It's normal, after all..." 

Karen knew that Ishigami was a man, so it was normal for him to get hard, especially when they had kissed each other so lewdly like that. Yet, she had to say it was—

'It's huge...' 

"...don't touch it." 

"I won't!" Karen pouted and asked, "What do you think I am, Ishigami-kun?" Even if she had kissed him, she would have had common sense and wouldn't have touched his stiffness, but considering how huge it was, even if she didn't touch it, somehow, she could tell that it would touch her when they were so close. 

Still, because of this, she understood that that huge and hard thing, which she felt before, wasn't his smartphone but something else.

"..." 

What do you want me to think of you? 

Still, Ishigami understood why that gentle and yasashi harem protagonist would stop the girl and say, "Don't do something that will make you regret it," when the girl was about to make a move on the protagonist. 

Unfortunately, he just accepted and enjoyed the kiss, so he knew that their relationship might develop further, but—

'I really am a scumbag.'

"...did you regret it, Ishigami-kun?" 

Ishigami stopped his thoughts as he was startled by the sudden question thrown at him. Staring at the girl before him, who looked at him calmly yet couldn't hide the worry in her eyes, he said, "What am I regretting? I have a cute girl like you who took the initiative to kiss me like that. Instead, I think that you should regret giving your first kiss to a scumbag like me." 

Karen smiled and leaned on him again. "Yes, I regret it a lot." 

"...should we do it again, then? It is said that a minus times a minus will be a plus."

"....." 

Karen was speechless, wondering how Ishigami could come up with such a conclusion. 

"This isn't a mathematical problem, but let's do it." 

As their lips touched against each other, Karen could feel her body shiver with a pleasant sensation that could be felt on her body. It felt wonderful despite how wrong it was, but she knew well that, like Kaguya, she never regretted her decision to date Shirogane, even with a huge difference in status and wealth between them. 

Even if Karen knew that this guy was a scumbag, who had been with many women, she didn't regret her decision to kiss him for the second time. 

Yet, while she wished to be together for a little longer, their time was limited as the school would end soon; while reluctant, the two parted away with Ishigami, who was still in a daze, realizing how lucky he was. 

Still, this was good, he thought. 

Love is like learning a language. 

The more one used to it, the better they were at it. 

More importantly, no one would teach him about love, whether it was at school or any place, so all one could do was learn it by oneself since the experience and teaching of others were far more useful than one's practical experience. 

Yet, he had to say, he had learned a lot from all of his experiences, so even if what he and Karen did at the school was pretty risque, no one was able to discover them, but if Karen's friends discovered them, then led into a situation when he would be all of Karen's friends, they might—

'It's all fantasy, of course; such a thing won't happen, right?' 

A man needs to learn from his mistakes. 

Ishigami had been in many problems after being discovered by many, so he tried to fix his carelessness problem, which was quite successful, but he knew well that he had to stop seducing others at this moment. 

As he thought so, he decided to stop thinking of those problems since as he had made up his mind to be better and improve his power, he decided to visit the luxury brand shops in Ginza, such as Cartier and Omega, to buy a watch for himself and his father. After that, he went to visit a Hermes store to buy a bag for his mother before going home and saying, "Dad, can you help me buy a company?" 

"....." Ishigami's Papa and Mama. 

The two were in silence, watching their son, who had given them luxury gifts for them. 

While they were happy, they had to say Ishigami's words stunned them silly, and if Ishigami wasn't a high school student, they would ask whether he was drunk, but as they looked at the amount of money in his account, they asked, "...did you rob a bank?"
