Hinata and Sakura run into each other outside the Hokage's office while Boruto and Sarada are still on their journey to find Mitsuki. Surprised, Sakura greets Hinata and asks if she's here to see Naruto. Hinata says that she came to bring Naruto a change of clothes, but she seems solemn.
Sakura is about to ask Hinata what the problem is, when Hinata suddenly apologizes to Sakura. Since Boruto was the one who convinced Sarada to leave the village, Hinata feels like she is to blame for what will be Sarada's eventual punishment for defecting. Sakura smiles and tells Hinata that Sarada's and Boruto's choices are their own, and Hinata has nothing to apologize for. All that Hinata and Sakura can do is pray for their childrens' safe return.
Among the Fans
SakuHina is a relatively well-known pairing throughout the fandom. As both Sakura and Hinata are each one of the most well-known female characters in the series, they are often compared to and set against each other as 'who's better' by many of the members in the fandom. Also, as both girls have a connection to both members of the SasuNaru pairing, another reason why this pairing is shipped is because of the similar feelings that these two characters hold towards the one they have feelings for in the series. Their rival pairings are NaruSaku, NaruHina, and SasuSaku.
