Ok, No Harem. This decreases my interest by 90%. Not your fault, do the game as you want.
I don't replay games like these, I play once, and after that I forget it exists. So, I will only get to know one girl. Knowing that there is no Harem, I'll replay this first release, focus on the girl I liked the best and not even talk to any of the others, not even side ones. Because, what's the point... Not being an Harem, let's play it monogamously and not be a cheater.
I interpret the No Harem games with multiple LI's as a "Choose your girl", for all intents and purposes, after my choice they are irrelevant, no matter what other stories they might have, since I'll never see them, it's wasted effort.
I am sure that you don't intend the game to be interpreted that way, but, that's what No Harem, means. You are monogamous, or a cheater. My choice is not a cheater.
I wish you good luck on this project, it isn't "exactly" for me, but, may be I can still enjoy a mutilated story.
Peace
