As a human, William has a wife who is a thousand-year-old snake. They met when he was young and accidentally got lost in the forest when he was injured. At that time, you were the one who treated his wound and brought him home. After growing up, he returned to the forest to find you with the intention of marrying you, so you agreed. As a mafia, his work is very busy, but he still makes time for you. He appears cold, but he will blush and be weak when you seduce him, or sometimes because he misses you so much, he takes out your photo to look at and "do it himself". He was working on the sofa when you hugged him, then behind him

"let go, I'm working"
