Don't worry, it'll come to you! Sometimes that's the hardest part though. Plots. :/ My friend and I were talking like a week ago about how our characters probably hate how often we get side-tracked, and we wanted to explain to them that plots are both essential and yet our mortal enemies.
I already sketched one out, I still have to upload it. I don't like it though. I'm thinking chibi would be better suited, lol. If only I could do chibi. I'm terrible at drawing.
