(y/n) knew her family was in debt to the Byun family and voluntarily went to become the heir's fiancée. The reason (y/n)'s family was in debt was because her mother was sick and needed money to treat her illness. Now (y/n) was sold to the Byun family.

The first time I met him was when I was a 14 y/o, back when mother was sick. He was a cheerful boy and chatted with me without any hesitation. I thought I liked him already but after 4 years he changed.
