いや、自分はただお兄ちゃんの方から手を出すインモラルな真尋✕みはりが見たかっただけで……

原作の真尋君って絶対みはりちゃんに手を出しそうにないじゃないですか、優しいし、妹のことを大事に思ってるし、そもそも性癖的に妹に興奮できないし
みはりちゃんも非常識に見えて、"研究方面以外の"倫理観はしっかりしてるんで素直に応じないと思うんですよね

だからコンプレックスを起爆して、真尋君のメンタルを歪めて優しさとか大事な妹って部分を取っ払えば、みはりちゃんを抱いてくれるんじゃないかなって……（虐待目的とはいえ
みはりちゃんもお兄ちゃんが大好きなんで、罪悪感って言い訳さえあれば素直にお兄ちゃん受け入れるんじゃないかなって……

自分の中では真尋君は溜め込むだけ溜め込んで自壊するタイプだけど、何かの間違いでも一度手を上げてしまったらどんどん決壊していきそうなタイプでもあると勝手に思ってるんですよね
ママがいればストッパーになるんだろうけどいなかったら…ね？

No, I just wanted to see an immoral Mahiro x Mihari with Onii-chan making the move...

The original work's Mahiro-kun would absolutely never lay his hands on Mihari-chan, right? He's kind, treasures his little sister, and in the first place he can't get turned on by his little sister. And while Mihari-chan seems to lack common sense, her ethics "outside of research" are sound and I don't think she'd obediently accept everything like this.

That's why I wondered if Mahiro-kun's complex exploded, had his mental state warped, and stopped treasuring his little sister, then maybe he'd take Mihari-chan... (even abusively) Mihari-chan loves her Onii-chan too, so if she had guilt as an excuse, then maybe she'd obediently take whatever her Onii-chan does...

Mahiro-kun in my mind is that type that lets things fester and fester until implosion, but if he ever raised his hand once even by mistake, then I feel like he'd let everything burst out. Their mama would be a stopper if she was there, so if she wasn't... You know?
