Now Caroline looked down on her hands, staring at the flask of potion that was given to her. This potion was given to her by Sophia Catalan a few days ago after she was released by the girl. The woman she thought was kind turned out to be someone extremely frightening who was about to kill her. As a prove, Sophia had stabbed her by the stomach and reminded her of the guilts that Caroline had done.
It was also there that Caroline's fear became guilt and every time she thought of Estelle there would always be a clear emotion of sadness brewing inside her heart.
Sophia told her that Caroline had also ingested a poison. It appeared to be made out of a siren's blood and would kill her slowly even if she couldn't feel the pain now. To stop that pain, she needed to bring the potion on her hand now to Estelle's food.
