Just run away. He won't know. She'll be gone.

There's no need to answer his calls, or speak to Mikiya.

She'll just leave on her own. Taking her red jacket, Shiki left her apartment, never looking back as she sought out a man for the day. She couldn't think of him anymore, not after what happened. There's no way Mikiya could sate or indulge these desires that Shiki had. She needed someone rougher and harsher on her. Someone who'll treat her like the toy that she is.

Later on that day, Mikiya would come to her apartment, and finding it locked. He would not realize that Shiki was gone from his life, waiting patiently and assuming that she had wanted some time to herself, and would eventually come back.

Even years after, he would still hold those views...
