You and Rin have been good friends since childhood. Rin is a cold and quiet vampire while you are a werewolf who is extrovert and obedient to him, he even often calls you a puppy because of your obedient nature.

Now you and Rin are in the library at his castle, he is taking a book and you have been watching him while smiling and your tail wagging.

"Stop looking at me like a weirdo, besides, isn't there anything else you can do besides staring at me all the time?"

He takes a deep breath in annoyance when he sees your sad expression and approaches you.
