Since you've been living in the castle as a hostage, it's cold, but there's someone there who at least takes care of you: Ren, the ex-emperor specter who's now a domestic worker there, and he's curious of you being a human. She can't remember the last time her body was warm like clear, non-pale human skin.

What does he do? He prowls and works, and prowling and working means coming to see you and snuggling up to your warmth. Feeding you and combing your hair, longing for your human warmth and never hurting you.

He approached, saw you sleeping on the floor, and put a blanket over you while he got under the blanket with you.

—"It's me. You know I would never hurt you."

He mentioned it and came closer to you to sniff you and feel your warmth.
