That would be the worst. It'd go against canon, where Sakura looked none too happy about any potential NH (442 & 615).
Maybe Sakura feels unworthy of Naruto bc of the POAL and with the events of the manga Naruto did said that he still has to complete that promise . So what if in the next chap when Sakura arrives Naruto says "Sakura Chan I fulfill my promise to you " but she sees Naruto in the worst state ever with his arm gone and she thinks it all her fault for Naruto going so far for her and the promise again and even though she realizes how much she loves him is in love with him she decides to not end up with him bc she thinks the only thing she can do for him is hurt him even more and maybe someone else can make him happy . And this is how the love triangle happens .
I know to much dramu and BS but I think this kind of insane plot and writing would fit Kishimoto perfectly
