I could never be a protagonist because I’d just never move the plot along. “You have free reign of this castle, but don’t go into this one area” Okie dokie. I mind my own business and hang out in the library. Queen of staying in my own lane. I’ll never discover your magic curse.
I genuinely want more stories that operate like this, the protagonist has to end up discovering the super secret thing in a way other than ‘went exploring in one place told not to’
Maybe they found a secret passage so they didn’t know they had ended up there
