100% the story here makes a harem untenable
That being said
Joshy92 -- I often play harem games because the huge majority of devs make nothing but COW tits
as I truly enjoy and prefer the "below B cup" lady if it was not for harems I would have maybe 7 AVNs to enjoy.
Also not all the stories are bad and the better formula is to start with a Queen of the harem who wants to add women and put in reluctant women or women who take a while to be convinced so they are not just 100% on board after 2 sentences.
For this VN I was resigned to having only Lucy to be of interest but man DB did a great job making Emma just have that... something in how she is written that makes me like her so much in spite of her not being more petite (small tits) or a redhead. So it really is a compliment to the writing that I am so into Emma.
