Please help me remember a manhwa. The plot goes like this:
There is a poor noble girl who is ostracized by high society. One day, she is possessed by a ghost of a villainous girl who was beheaded in the past. This villainous girl, if my memory serves right, wants revenge since she was wronged or set upped in return she helps the poor noble girl.
