If You Want a Cheeky Sorceress [Novel]

Betrayed by her fiancé and friend, Roxiana Franche lost her family and was reduced from a princess to a slave. As she was being sold, branded as a slave, an unexpected salvation came in the form of a tiger-like man, appearing amidst flames. "Princess, you just eat well, sleep well, and live well in this comfortable, luxurious palace." I pleaded to be allowed to die, even offering to become a wicked temptress, but... "Yes, Princess. Even bite off my finger and chew it. You need to eat and swallow something to even stand up to my mockery." Why do you keep trying to save me?
