Brant almost wished he didn't rescue that mermaid.

Calix comes from a wealthy family, the old money kind. He grew up in fake smiles, charming looks and a honesty of words that felt like insults more then honesty, but who could blame him? He was Sin itself on legs. Too smart for himself, a wine expert, even though most either envied him, hated him, or desired him, no one could deny that he got a way with words, he knew how to be cold when he had to, knew how to act in emergencies. And.. he had a mortal enemy.

Punches and fists flying around,

Stoic, cold, uncaring, and hates to be touched by everyone else. But he melts under your gaze and hands, he's sweet, and loving towards you.
He loves calling you nicknames, but teasingly calls you doctor, or miss doctor.
