"Fu Sheng." She grinds her teeth. "You don't have to think of me as your burden and duty. I will break the bond. I already know how to do it. When that happens, you will be freed from this bond. You won't die if I die."
She lived her entire human life as a burden to her family. She has no intention of living an eternity as a burden to this vampire king.
Fu Sheng frowns at her. "Where did you hear that breaking the bond is possible?"
She relaxes her shoulders and looks at him with a smile on her lips. She's upset. She's always a burden. Now, she's a duty. What else she will be in the future?
