"Can you two be mine?" 

Ishigami decided to become a scumbag. 

He knew that this might be a hasty decision and he might be beaten up by Kobachi and Tsubame, but this was what he wished for. 

By becoming a scumbag, the two of them would get angry at him, beating him up, then leave him. 

However, with this, the two wouldn't fight anymore since there was no need to fight for a sleazy guy like him, right? 

While there was part of him who, being greedy, wanted the two of them to be his at the same time, he knew that, like Chika, Onodera, or even Kaguya, Tsubame and Kobachi were proud, and they had never thought of their man to anyone. 

Previously, when Yume Atenbo asked her whether she could sleep with Ishigami or not, Tsubame, while she didn't reject her directly, refused her in an indirect way as she had wanted him to be only for hers. 

There was no doubt that under the guise of that gentle senior, Tsubame was a strong and selfish woman who wished for her loved one only for herself, and to do that, she would do anything. 

As for Kobachi, was there even a need for a question? 

Considering her dangerous conduct, it was already amazing that Kobachi didn't expose everything to Onodera, so he could only be for hers. 

Nevertheless, whatever their thoughts and feelings were, they were only one-sided, and Ishigami also didn't want to be conquered by them. Moreover, if he even did that to Chika, who was the granddaughter of the former prime minister, then how could he give them special treatment? 

Yet, this was also a bet. 

If everything ended up failing, the two wouldn't become enemies and would not fight anymore, which was also good as he didn't want them to become an enemy. 

However, if he succeeded, then... he would gain happiness. 

Though he knew that his wish might be a little hasty to express, and probably, he should have said something, telling them a story of how they meant and how they encountered to be, yet in such a situation, it was already amazing that he could clearly express his intent, and he had to say, it felt great when he was able to say everything. 

Hiding everything from the two was hard, after all, so when he could tell the truth, everything felt at ease, yet he had to say, it was also nerve-wracking since reality wasn't a harem comedy story, where the women would scramble around the protagonist, giving him a feel of their bodies, or even giving their everything, yet at the same time, the reality was stranger than fiction. 

Whether Kobachi or Tsubame, they could only stare at Ishigami in silence, who expressed his greedy desire. They had never thought that those words would come out from his lips. 

Scumbag! 

This was their first thought when they heard his wish, and there was an urge to beat him up, yet this also made them calm. 

"Yuu-kun, can you leave first? I want to talk with Kobachi." 

"Go out, Yuu." 

"....." 

Ishigami was speechless, but he didn't leave. He stared at the two and said, "You two won't fight, right?" 

"We won't." 2x

The two answered at the same time and also understood his concern; after all, they were about to get physical and cause a big problem that might cause another round of huge scandal in this school. 

Their heads were clouded with their ugly emotions before, but due to his previous words, they also started to calm down, and whether it was Kobachi or Tsubame, while they wanted to beat this guy up, they didn't want to make anything bigger. However, there was no doubt that they had to settle the uncomfortable feelings in their hearts, and they needed to talk to each other, or else they knew those feelings couldn't be solved and would stick in their hearts, making them agonized and in pain for so long. 

So, they had to talk about this matter, but they didn't want him to listen since this guy was such a bastard! 

Still, even if this guy was a bastard, their feelings were impossible to erase, and they wanted to solve the knots in their hearts as soon as possible. 

"Okay." 

Ishigami didn't force himself to stay and knew that he had to leave so the two of them could solve the knots in their hearts, but—

"But I will stay outside the room." 

Kobachi and Tsubame nodded and said they didn't mind him staying outside the room since they knew that he was worried about them. 

Still, watching his retreating back, the two felt ironic since he had become the person that he hated the most. 

Ishigami received his stigma because he wanted to protect the smile of the girl who was being cheated on by a guy, yet now, he had become the guy who cheated on his girlfriend. 

Yet, the problem was he didn't cheat on his girlfriend voluntarily. Instead, he was being seduced, but he didn't reject them, and they were also happy with his acceptance, so... then... who was at fault? 

If they had asked this question, no matter how long it was, it would have been impossible for them to come up with an answer, but while Kobachi hesitated, Tsubame came up with her answer. 

"Koba-chan, have you slept with him?" 

"What?!" 

Without waiting for Kobachi to recover from her surprise, Tsubame continued with her question. "Did you have sex with him?" 

Kobachi was stunned by such a straightforward question, and her face blushed with embarrassment. 

Even without an answer from Kobachi's lips, Tsubame could tell the answer from Kobachi's expression. 

"Then, I think that you should rethink your decision for him." 

Tsubame looked at Kobachi with a calm expression and said, "You still have your virginity, and you are beautiful. There are many guys who you can choose from: those who are richer, love you, and think of you as the only one for him. There are many better guys that you can choose from if you want to. What about Kazeno? He told me that you were cute and thought to—" 

"NO!" Kobachi cut Tsubame's words, taking a deep breath as she tried to calm her trembling voice. "Only him... no one is but him... I only want him." 

With a trembling voice, she uttered her feelings toward Ishigami. 

Tsubame was in silence, staring at Kobachi, who had such a deep feeling toward Ishigami, thinking that this guy was lucky, and that was why she wished to beat this guy up! 

Taking a long, helpless sigh, she said, "Then, it's even better than you think carefully. You shouldn't give everything to him so easily, so he will treasure you better and think whether he is really worthy of your love and loyalty." 

"...how about you?" Kobachi frowned as she looked at Tsubame, who appeared so mature and calm as if her feelings toward Ishigami were unwavering. 

"Me? I am different." 

"What's the difference between you and me?!" 

"I have slept with him." 

"...." Kobachi.

"So, even if it's wrong, I want to try to be with him, at least..." Tsubame looked at Kobachi with a gentle smile and said, "He is being honest instead of hiding everything and putting all the blame on all of us, even if we knew who seduced him in the beginning." 

Kobachi didn't say anything since if she didn't give Ishigami a chance, then would he make a move? 

It was because he made a move that she could feel all of this happiness. 

Yet, could she really share him with others? 

"So, think of this carefully." 

Tsubame took a deep breath, trying to calm herself since even though she was older, she had to say, this was her first time to meet this situation. "Then, I will leave first. If you want, you can stay here for a longer time. Here is the key." 

Kobachi didn't refuse and accepted the key, yet, she couldn't help but look at Tsubame, who was about to leave and call her. "Senpai!" 

"Hmm?" 

"H-How was it...?" 

Her voice was quiet, and Kobachi didn't even express clearly what her question meant, yet Tsubame understood clearly what Kobachi wanted to know, but unlike before, this time—

"Try it yourselves."
