Sakura's role in boruto or lack thereof is my personal reason why the boruto series does not fit into the naruto narrative. Sakura is a person that would directly involve herself in the current situation. Sakura would have had just as much exposure to him as naruto.

Assuming you want an english version, sakura no uta doesn't have a localization so you can't buy it translated. And iirc, there's no fan translations in english either. I don't know if somebody noticed, but sakura really looked happy in the entire coachella performance.
