Reincarnated into a Duchess

(This my original novel) Duchess of the Latemian Empire’s troops - Adriana Fentur. Well that is the body’s name. The actual soul’s name is Tia Garder. A 10 year old soul from the 21st century who was isekaied into a romance novel which took place in a fantasy world. She didn’t transmigrate into the protagonist’s body, but instead into the pitiful second female lead who was obsessed over the male lead. In the end she was beheaded because she rebelled against the empire using her army. She opened her eyes to first find herself in front of two coffins. But, this time a person who was unknown in the novel started courting her. — — — — “Who are you?” “Me? I’m your best dream.”
