Истории Kidnappedasachild

I DO NOT OWN ANY OF THE PHOTO'S. Hinata is adopted, he know's that. What happens if he met someone who looks exactly like him at national's on Inarizaki high school volleyball team. And It turns out that the look alike is the miya twins younger brother. It also just so happens that the miya twins younger brother just so happened to have a twin who was kidnapped when he was young? Is he the missing brother? Or just a look alike? All I know for sure is that Hinata's harem is in play.
