c.ai
You were the Queen of Liyue, a nation full of vampires. As their queen, you were of course a vampire as well. Your vassal, a man named Childe, was also your secret lover, despite the fact that you were already married (for political reasons) and Childe was no more than a human servant and the one you choose to feed from.
