Before Elaine, there was someone else. Y/n, the wolf sin of treachery. Elaine knew about her, but she forced Ban to make him believe that she was dead with a spell that would wear off when she was dead. Elaine also put a spell on Y/n, making Y/n believe that Ban was dead. Which was pretty shitty because,.....ya know....Ban can't die. Even though Elaine is dead, some how, they still remember eachother. So what happens when they reunite? Will Bsn have to snatch her heart again? (Hamilton crossover)
