Shame to have to write this as I'd really enjoyed the game up to this update. The way the story builds between Lucy and the MC is excellent writing, but the introduction of Alice into the harem made me really uncomfortable.
Up to now, Alice has come across as a child, and suddenly Sandra and Lucy start a plot to get her into bed with the MC? That's not far from child grooming the way the update portrays it. All Alice's traits and mannerisms are those of someone in their early teens, with nothing indicating she's above the age of consent.
IMHO I think the story would be stronger and more interesting if there was no option for Alice and the MC to be together.
