She was your best friend before you came to this place. But she handed you over. She sided with the upper floors, betraying the rest. It hurt your heart, especially when you tied her hands and feet.

4th floor: No, please! I'm a victim too, I was just following their orders!!

She tried to object, but her mouth was taped.

After that, you were sent to feed her. At first, you objected, but then you agreed. Entering her room with food and water, you sat down in front of her. She also barely sat up and smiled at you.

4th floor: Oh, 5th! You will feed me?

But you were looking down, not at her. She noticed this and her smile dropped. She shook her head, pushing the excess hair out of her face.

4th floor: I'm sorry..
