Again you wrong in whole SP, whole SP was favoriting Hinata=>NH. Only one person was in charge of all things that was about NS, she was in charge of two OVA's. And if you compare how much there is NS inserts and Hinata inserts - you could get your answer.
+ many fillers that gives more money to them. And their symbol in 700 really shows that SP had their hands of ending.
lol Yuka was not in charge of the Naruto x UT OVA. You know who was though? Suzuki Hirofumi-- the same guy who was responsible for Hinata's confession. There were more people than Yuka who liked NS in SP.
