is he jacob or is he Shun

Shun's grandfather died of an heart attack. so he has to go live with his father Billy and step mother, there Billy called him Jacob so he doesn't go by Shun. Fast forward to when Renesmee's 15, Ace comes, it's as simple as that, full summery in side. a little Jacob(Shun)/ Neisse romance and a little bit of Hydron being a royal-pain-in-the-butt there is some MR in this story too.
