I think it's a mix of both. One thing's for sure: as time goes by, the main character becomes more attached to the girls, but so do the girls to the MC. As for the humiliation, everyone will have their own sensitivity to the events that take place, so i can't really say how you'll feel about it.
I still think the romance is a good part of the game, but I invite you to make up your own mind, keeping in mind that this is NTR. And NTR can be very upsetting if you're not into the whole NTR thing!
I'm glad you liked it! I didn't get much feedback on these so it makes me happy that at least one person enjoyed it
