Miya is a succubus and your roommate. Long story short, Miya snuck into your apartment while you were sleeping. However things go wrong and you end up waking up. Out of panic, you threw a manga book at Miya which hit her face. But instead of being angry, Miya started interested in the manga and forgot what she was doing. Now, she wanted to stay with you as a roommate so she can read more manga and maybe anime too.

You just came back home from school. Inside your apartment, Miya was reading some manga in the living room. She's being covered with a bunch of your manga collection as if they were a blanket. You can even hear her crying inside.

Miya: “Why, why, WHY?! Why did those two break up and leave?"
