please help me finding this fanfiction T_T

i forgot the title of the story and I can't seem to find it in my bookmarks.

the plot is that she was kidnap by baekhyun and brought her to a mansion where exo k tries to kill her but, she was actually an undercover agent and she work with lay to solve the case of missing girls.

 it has two alternative ending first, suho killed her by injecting with some kind of drugs in the hospital and second one is where she got pregnant by baekhyun and they had an happy ending when he was out of prison.

i think in the story baekhyun was a painter whose painting are about the 7 deadly sin and suho was a doctor where he sells the organs of the girls they had killed.

the plot twist is that it was only an tv drama of exo ^_^
