If you suggest to start a harem, you will be able to have group sex with all the women you're currently in a relationship with. Dismissing the thought essentially closes this option off for the characters involved.
A full harem won't be possible in that case (if you dismiss the thought), so it would exclude Céline and Lilly. Separate relationships for each girl are also a possibility, but that's another branch in the game.
so a waste of option for harem,and time wasting extra storyline for you,i guess,well good but isn't there any other esy way for you,to give that option rather than making a complete storyline for that?
