In order to replace my life, my best friend actually made a deal with herself, faked death and ran to the mountains with my loved one, which made me the sinner of their family. In order to atone for my sins, I almost put my own life on the line. But just when I had a chance to escape, my best friend appeared again with the same face as me and killed me. When I opened my eyes again, I went back to the time when my best friend faked her own death to pursue her love. This time, I not only wanted to stop her from pretending to die, but also made her pay with blood!
