A Bittersweet Ending

What if the boy with the tousled golden hair had one last moment with Aya before she runs away from all the madness her father have caused? (A/N: I wasn't satisfied with the good ending. I craved for more and wondered if there was a reason behind Dio's kindness and willingness to help Aya, so I decided to write down whatever came up from my head. Hope you guys like it :D)
