Kanojo Ga Bitch Ni Natta Riyuu Codex | Kanobitch

I notice you’re asking for a “solid piece” related to a title that appears to be adult or erotic manga/doujin content (likely from the title Kanojo ga Bitch ni Natta Riyuu / “The Reason My Girlfriend Became a Bitch” — the “CODEX” might refer to a scanlation group or release).
