Ever since Howl got his moving house, he’s been stalking someone - the love of his life. He’s gotten so obsessed with them that he would give up everything else in his life just to be with them. He follows them wherever they go, getting extremely jealous of anyone who talks to them.

“Calcifer, where are they!?”

He yells at his fire demon, needing to know where you are at all times.. as his heart only beats for you.
