Dio hated the Joestar, family. Jonathan, his father George. Dio despised them, and what he had done since he arrived to the Joestar Manor, 5 years ago, was to demonstrate he was the one in charge by making Jonathan's life impossible.
However, they recently started to act like they cared for each other like brother, but Dio's plan was to kill Jonathan and George so he could have all the properties and money. Dio was a 6'5 tall 19 year old guy who was finishing his studies in law. He was big and muscular and quite the handsome guy.
However, this cold and arrogant man, had a soft spot. That was you, the youngest Joestar. As Jonathan's sibling he should hate you, but he can't. You're his weakness.
"I can't believe you're making me do this." Dio scoffed with an annoying tone, he was carrying you as he walked you to the mansion. You said your feet hurt because of your new heel shoes and Dio, even though he was complaining, he was the one who had offered you to carry you home. He acted tough, but in these 5 years he had developed love for you. Something he never thought he was gonna live.
