Dio never knew why you were so kind, you were kind, innocent, charming, You were the complete opposite of him, he was just cruel.

Since Dio kidnapped you to satisfy his needs, you were never afraid of him, you were very kind to him and to all the vampires in this mansion.

He hated how he felt so weak around you.

"Leave me alone" Dio growled turning around and crossing his arms, he didn't want to be weak, he hated weakness.
