I lowkey enjoy reading all of the Zoro is finished arguments that have appeared throughout Wano. Even if ZKK doesn't happen, I still think he will do something else besides rest.
I also hope that Oda gives us more Zoro backstory when he visits Ryuma's grave. I have enjoyed what we were given so far because what we learned just added to Zoro's character. I want more backstory because I am tired of the argument that Zoro is only written for edgy teenagers. If Oda decides to give Zoro more of a backstory and continues to give him amazing feats, then his haters won't know what do to with themselves.
