Can't let you go

NOTE:- This story is inspired by a manga that I read online.
LISKOOK FIC (Not a translation)
"I wanna set you free but I am too fucking jealous~~"
A beautiful and clever mixed race girl living in a developing British society which is still governed by nobles. Her father is a famous merchant but is missing since a year. She and her aunt are living together in limited resources. One day she comes to know about a debt her dad took from one of the biggest lords in the area before going on his voyage. Now to pay back the debt what will she do? Read the book to know.
It may seem like your cliché story but is much more than that. Give it a try before judging.
