Lol no, have you not seen sakura faces throughout gaiden? Especially when sasuke rejected her kiss lel. Sarada didnt even know her and even in the movie promos it says shes has indifferent feelings towards him.This, really. Plus in those rare moments we've seen Hinata (1 panel in the gaiden + movie trailer) she seemed more unhappy than Sakura, at least to me. Furthermore, Sarada adores her dad, while Boruto hates his own.
