——I never believe that there are ghosts in this world, but I believe that there is a devil living in everyone's heart.
My name is Xia Yurong and I am a psychiatrist. At this time, the elegant and beautiful girl sitting opposite me is not my patient, she is my half-sister, Xia Yuge.
I don't know if it's an occupational disease, but I always like to talk to her. Although our awkward identities are destined not to make us as familiar as real sisters, we still try our best to adapt to each other.
