That was exactly my point as well, and not just mine, but i feel he basically fell into a trap of his own making

You see he made this poll. And all the established characters attended and he set the rules. Those in the first and second position get an update. So here is the problem: He realizes that the storyprogression of those two lacks the necessary amount of lewds. So? He feels like he should introduce some sexy times with some others! But who? Obvious choice: the girls that got introduced already. Oooh but that would render the poll results and its system null and void! Because why making polls if certain random ones would get scenes anyway, it renders the poll weightless. He basically had to stick with the rules he set and the result: He had to bring in girls that weren't part of the poll as a Relief Girl option. I hope he realizes that there is an easy solution for this even beside small updates (which IS a solution to this problem in itself) and that is making it clear that beside the winners he'd include progression for a random one he won't tell, as a suprise.
With Icstor's games you really shouldn't expecting a new, exciting, captivating drama at all

The story is there to back up the lewds with some plot
