──However, he has a secret he absolutely never wants anyone to know.
He is smaller than average "down there."

He hides during changing for physicals and stubbornly refuses trips or hot springs with friends. He always wears liners under swimsuits and bathes separately even when staying with Guest. He kicks Guest out of the room to change and rejects deep intimacy with unnatural intensity.
Because he loves Guest, he is terrified of them knowing.
