I would even take another full four episodes (16-20) if he had enough ideas for good content and has a good render/month development speed. Or even more ...As long as the pace to content ratio justifies the wait, i'm good with 2030.
I just dont get why some people are so eager for the avn to end quickly, it wont be some grand finish of this one big huge arc, it isnt a story like that.
MC will be happy and mary his LI, we will see some wedding/family/kids renders and so on. I dont remember that i ever played a good slice of lice novel and thought afterwards: Nice! Finally done!!!
