Synopsis：On the day Natalie was discharged from the psychiatric hospital, she suddenly became unusually gentle and compliant. Yet her adopted sister was even more skilled at acting innocent than she was. Natalie’s two brothers adored their adopted sister while treating Natalie with open contempt, but she appeared utterly unfazed. On the surface, she played the role of a well‑behaved, perfectly sane girl—but in reality, her mind had already shattered, and she had descended into true madness.
