Naruhina is canon , naruto volume 64 cover made by Kishi is Naruto holding hands with Hinata , in Japan holding hands means love , we also have the chapter where they hold hands and a note from editors "Never leting go off that hand" so people who don't see Naruhina as canon are in serious denial ,
About sakura kishi said , no secrets , normal girl , normal parents , kishi failed to make her a heroine or even a good support character , she cries alot , her plot relevance is low , and the manga is ending..... she could save tsunade even surpass her but that would not help the story , stop the denial chatte and stop spamming the same thing... the argument with the symbol and naruto BM and Hashirama was already wrote by you in other threads , sakura is a normal girl and a medic !
PS. Kishi also said that Sakura is good at genjutsu in part 1 yet until now she did not use genjutsu ! Part 1 and Part 2 are very off points with many contradictions , kishi is human with good imagination and not a great writer....
