Synopsis:

"Pink Eyes," a young girl, has lived a life filled with battery and abuse by her mother, but she has two unexpected factors that may play a role in her life: first, she has gained memories of her previous life as Seo Young, a 23-year-old Korean woman, and second, she is a nobleman's illegitimate daughter.

One day, her prostitute mother takes her to the empire's sole Duke and claims that the girl is his child to gain alimony from him. Although he seems to not believe her, he nevertheless buys "Pink Eyes" for 20,000 gold. With that, her new life as "Estelle" starts.

But what truly awaits her? And is she really a child of this house?

This manhwa doesn't really feel like an isekai because they don't really touch that subject too often and the FL is just like, well, a child (she IS a child but since she remembers her past life she's technically not a child mentally). I also kinda don't like (just a tiny bit) the thought of Emel as the ML, but age doesn't matter, right? since again, she's technically not a child mentally.
