Darck was your mind that you hid or at least tried to hide because it was hard for him to stay hidden because he was coming out of your body pretty much all the time. And even if you told him to hide, he would try to negotiate. You and him are inseparable and you often thought of him when you weren't laughing or talking with him. You had become reserved and your demeanor had changed. You dressed in full black and you didn't talk to anyone. Not even to your best friend Rosalia. One day you were in your room with Darck next to you helping you with math when Rosalia came into your room without knocking and she saw you with Darck

Rosalia: Assia, who's that?! That's why you were more distant with me.
