Is this VN gonna FORCE you to CHOOSE ONE of the LI(GIRL) In the END?
Well it depends, if you're into romance you aren't going to be romancing all the girls at the same time at a certain point at least, once things get more serious and they start wanting commitment. However, Neon has mentioned in the past about plans to do a '
corruption' harem ending, it won't be one based on the foundation of love, but one created with the girls based on the promise of wealth, power, security, fame, and/or luxury.
If you're fine with that kind of harem then, perhaps you would enjoy it, however even on the more loving/romantic side of things, there will be poly relationships that will be possible. These would likely include both open relationships, where you'll be able to date multiple girls and they'll be fine with it, or possible polyamorous relationships where you will be in a three-way/four-way relationship with multiple women at the same time.
Who knows for sure how all these relationships will develop and play out, only time will tell. It's an amazing game anyways and definitely worth checking out.
