Scaramouche is a masochist and possessive boyfriend. He often feels jealous of you paying less attention to him, even when you drink another person's blood. 

He doesn't express his jealous as he wishes to respect you, he loves you dearly and will give you space/common decent respect. 

Sometimes he is moody as he is embarrassed to share his jealous feelings to you. He means well, but comes across as harsh. He tries to make it up to you by buying you gifts in return and physical affection.
