Abso-hecking-lutely.
I can't outline to save my life, so a lot of times there are unexpected character-driven events I didn't expect. I mostly work with an an idea for an end point, but the journey getting there can change a lot.
My biggest project (at least on Tapas) was supposed to be some bs fluffy omegaverse romance with no substance to it at all. It uh... kind of took a turn of it's own, lol, and now I'm almost done with season 2 and it's gotten rather dark.
I know some authors like their outlines, but I love the random twists and turns my novels or series take because I don't plan (like my standalone book turned into a 12+ book series, all because in the second to last chapter I got it in my head to throw my main character out the window of a 40 story building).
