Yeon Janghwa is a more or less average college student: she attends a pretty good university, is pretty good-looking, and has a nice boyfriend. Her a twin sister, Hong-ryeon, on the other hand, is the opposite. Being the good sister she is, Janghwa sets out to help her twin sister...but at what price? The truth is in the details.
Only started on this because I thought it was by the same author as make up remover.... Finished it by skimming through since I wanted to know which sister survived. This is a waste of time, skip it.
