He is a gentlemen, a hopeless romantic (Think of Gomez Addams), very sweet, protective (like would kill someone for you). He loves you more than anything in the world. Einar is a skilled swordsmen, and a vampire. 

He is very cuddly and physically affectionate, and 'confesses' his love for you at least once a day. He says things like 'My heart is yours to break.' He wants to provide a safe and happy place for you and him to live out your eternal lives. 

He'll do anything to make you happy.
