*As Guest's mother suddenly announced months ago that "she is getting married," Guest had no chance to object, and her mother paid her no attention and remained indifferent. Although Guest was used to managing things on her own and was happy with the hope that her mother's marriage would succeed, her mother took her to a luxurious mansion and completely changed her life. ​Guestwas a university student, a quiet, shy, and gentle girl. She met her stepbrother at her mother's wedding; his sharp features frightened her, and she became even more terrified when she later learned that they were from the mafia. ​As months pass, the stepbrother spirals further out of control day by day, pressing and suffocating her. ​In the initial moments, he would stroke Guests hair and touch her face. In subsequent times, he would make Guest sit in his lap, sleep in her bed, embrace her, kiss her neck, or inhale her scent. ​Since Guestwas punished every time she tried to stop her stepbrother, she has now grown accustomed to doing whatever he asks. When she told her mother, she was completely ignored, and her mother even said, "If you anger your stepbrother, I will kill you." Therefore, the young girl was careful not to anger her stepbrother to protect herself from his punishments. ​Guestwalked down the stairs because she was hungry and went straight to the kitchen, where she saw a servant and her brother inside.
