Kasugano Sora's suspicion wasn't based on any special reason - she simply thought of Hoshino Miru's attitude toward harems: only one.
He planned to have them all.
Since he had said this, Kasugano Sora naturally suspected this was his thinking.
He could clearly make a move on her but stubbornly held back. He had the same attitude toward Eriri too. It was hard not to suspect Hoshino Miru's goal.
"Because making a move on me equals giving up on Eriri, so you're trying to endure?" Kasugano Sora's eyes were particularly unfriendly. She was super angry - no girl wouldn't be angry about this.
Seeing he couldn't deceive the girl, Hoshino Miru still embraced her slender waist.
"No, actually I already can't hold back anymore." Hoshino Miru slightly adjusted his posture so a certain place wouldn't be too prominent. "Is it possible that you were just a middle schooler before, really too young, and I was too embarrassed to make a move?"
Kasugano Sora was immediately silenced. She seemed unable to refute this point.
"What about now?" Kasugano Sora had wanted to keep a straight face, but the more she thought about it, the more aggrieved she felt. "You just rejected me."
"If I rejected you, then who was making those sounds in my arms just now?" Hoshino Miru touched her thighs - the feel was particularly silky.
Kasugano Sora didn't stop Hoshino Miru's movements. The lingering sensation still made her body vaguely tremble. She denied very shyly: "There... there were no strange sounds... Miru was bullying me..."
Hoshino Miru just smiled slightly, pressing against the girl's neck, continuing to soften his voice: "I like Sora, and Sora likes me too. Isn't that enough?"
"You're lying again." Kasugano Sora panted. "You're scheming something bad. You don't only like me."
"Lying? Are you talking about Eriri?" Hoshino Miru began tempting the girl. "Eriri has been our good friend since childhood. I like her, and she likes you too. What's wrong with that? Shouldn't good friends be together for life?"
Kasugano Sora felt somewhat confused. Was it really like that?
No wait - Hoshino Miru just personally admitted he liked Eriri!
"You really do like Eriri!" Kasugano Sora was very stubborn. "You can't like her!"
"Is it because Sora is worried I like Eriri more?" Hoshino Miru looked into the girl's eyes. "Don't worry - before I liked her, I first fell in love with Sora."
This confession was even more unexpected than the earlier fastball. Kasugano Sora felt her brain going fuzzy.
"The three of us are all good friends. Wouldn't it be a pity if we separated in the future?" Hoshino Miru continued tempting. "On some day in the future, without Eriri, who would Sora play games with? Who would you share anime with? Wouldn't life be a bit boring?"
"I... I can also play with Miru." Kasugano Sora worked hard to find reasons.
"That's right, I can also play with Sora. It's just that when everyone can be together forever, why choose to give up on someone?" Hoshino Miru's voice seemed to carry strange magic. "Does Sora want to see Eriri bring a man we don't know to visit our home?"
"It's different!" Kasugano Sora covered her ears. "You just want to get both me and Eriri into bed!"
"Is there a problem with that?" Hoshino Miru showed no embarrassment. "Must I give up on someone to prove my relationship with another person is better?"
This was the first time Kasugano Sora had seen someone speak of being two-timing so openly and honorably, not ashamed but even feeling glorious.
"Even if Eriri becomes my girlfriend, what of it? I'll still always like Sora, always be Sora's brother." Hoshino Miru continued. "Our relationship won't change in any way. No one can take away the sister I love."
Kasugano Sora bit her lip. This promise from Hoshino Miru was exactly what she wanted most.
If there were no Eriri, she might happily hug Hoshino Miru and act spoiled continuously.
But adding Eriri, Kasugano Sora was particularly conflicted. She completely didn't want to share Hoshino Miru with anyone.
It's just that having been with Eriri for so long, it seemed not unacceptable to include her. Kasugano Sora felt this idiot had completely no threatening power and could be easily handled.
No wait - she was clearly questioning Hoshino Miru, so why was she being convinced by him instead?!
Kasugano Sora held her little head. Damn it, how exactly should she refute him!
"Wait, there's also Mana!" Kasugano Sora finally remembered Sumita Mana and hurriedly said: "If Eriri counts, then Mana must be your target too!"
"I'd like that, but she probably wouldn't accept." Hoshino Miru said. "So what I'm thinking is the three of us being together forever."
If Sumita Mana accepted, he'd change it to "the four of us being together forever," right?
Kasugano Sora was indignant, though she also knew this wasn't very realistic because Sumita Mana was an idol - there was no reason for her to accept such an absurd thing.
"Is that Toyokawa-san also your target?" Kasugano Sora asked aggressively.
"Not entirely, because compared to her, I definitely like Sora more." Hoshino Miru answered.
Meaning that only if he liked someone at least as much as Kasugano Sora would Hoshino Miru add them to his harem plan.
Currently, Kasugano Sora was a special existence. Toyokawa Sakiko was now someone who could be given up.
Kasugano Sora wasn't very satisfied with this answer, but she could accept it.
"Hmph, no wonder every time you play games, you always choose all routes." Kasugano Sora pouted. Once she confirmed she was still the most special existence in Hoshino Miru's heart, her mood relaxed.
"I just can't stand seeing girls not being chosen." Hoshino Miru was very firm.
"As for harems and such, I suggest you give up quickly. No one would possibly agree to such a thing." Kasugano Sora huffed.
"If Eriri agrees, will you agree too?" Hoshino Miru blinked, as if he'd gotten past it.
Kasugano Sora snorted lightly. She wasn't an idiot - of course she wouldn't easily promise such a thing.
However, for Hoshino Miru, this attitude already revealed Kasugano Sora's feelings. At least it showed she wasn't particularly repulsed by what he'd just said.
If a harem situation really occurred, Kasugano Sora would probably half-reluctantly agree.
"I want to look." Kasugano Sora inexplicably became somewhat squirmy.
"Look at what?" Hoshino Miru was stunned.
"Idiot, it's not like I can't feel it!" Kasugano Sora restlessly twisted her body. "Hurry and let me see!"
"Wait, what's so interesting about that?" Hoshino Miru only felt his rationality was about to slip again, his body already getting restless.
"I want to see, I want to see! What if someone uses it before me?"
"There's no such thing."
"I don't believe it. If Eriri insists on attacking you, can brother guarantee you'll definitely resist?"
"..."
"Although I know brother hasn't dated anyone and is still pure, as for sneaking around, how would I possibly know!"
"If I really made a move on Eriri, I'd definitely tell you!"
"What's the use - it would be too late by then, so let your sister sneak a taste first!"
