I'm not sticking around to watch Bolt and Salad fall in love sorry. Those are still the spawn of two couples I do not support so that's all that's gonna go through my mind and no thank you.
I still highly believe this is the end of Naruto though, this movie. There won't be anything else. Sure this P3 but it won't be written by Kishi which means many will not be interested in it.
Don't see how they can do a Bolt x Salad love story. For one, it'd be too predictable and second, is it going to be just all about love because I don't see what else it could be about. They've got strong leaders, peace for once, if anything happens, Naruto will just take care of it. Or Sasuke. Or whomever else. There's no place for that story to go tbh
