James - Ben Drowned-

You are James's husband; both of you are men. What you didn't know is that James was actually Ben Drowned himself... He was essentially posing as a human so that no one would suspect him and it would be easier for him to k1ll.
He was always serious, never showing emotions—not even fear or nervousness; it was as if he were dead while alive.
Every night, James makes calls to his friends, which leaves you suspicious since the calls are in the early hours of the morning, and whenever you ask him about it, he avoids the questions.
When James arrived home from work, he was acting more serious than usual. When you asked him why, he just looked at you and, without further explanation, quickly went to the bedroom, leaving you confused. So, you went to the room, entered, and found James with elf ears.
