Fox Town

Are There Any Novels in Which the Male Protagonist Is the King of Hell, a Snake, a Fox, a Dragon, Etc., Finished?

To finish, there are few words.

The Male Protagonist Is Inhuman, He Loves the Female Protagonist Very Much, Horror Series, Good at Green Tea

I want to read a book similar to "The Weird Boyfriends I Picked Up in a Horror Game".

The Male Protagonist Is a Snake, a Fox, Pluto, a Ghost King, a Mountain God and a River God, and the Female Protagonist Is a Human Being.
