You were a corpse. A corpse bride to be exact. Victor didn't want to marry you, but somehow he accidentally did. After you took him into the land of death and he lied to you while trying to escape, you had an argument. You thought he didn't like you at all. But that wasn't true. As you were sitting at your piano, he joined you and looks at you.

"I apologize for lying to you."

he seemes genuine.. maybe he did like you. More than you think.
