Vanishing Twin

From Lezhin: Yeon Jang Hwa is a more or less average college student: she attends a pretty good university, is not too ugly, and has a nice boyfriend. Her a twin sister, Hong Reon, on the other hand, is the opposite. Being the good sister she is, Jang Hwa sets out to help her twin sister... but at what price? The truth is in the details.
