The woman didn't know what was wrong with the man and woman in front of unit 15-07 but she could tell that they were very worried about the woman who lived in that unit. She sighed before she said, "Aye, if she has really gone missing, you should call the police as soon as possible. There's something about that unit…"
She shrank back, suddenly bared her teeth and looked very frightened as though she had thought of something terrifying.
"What's wrong?" Shu Man asked in concern, surprised by the change in this woman's attitude.
