I haven't played this game for a long time. I have a question, I would like to start CH3, and I would like to see content with most women.
Are there any consequences when the MC is in a relationship with other women? How does it look like?
There are no consequences. Chances are that, in Ch4, he'll probably have a mini-harem consisting of either D, Elena, and Georgina, or D, Jennifer, and Georgina.
I'm still holding out hope that we'll be able to have a D, Elena, Jennifer, Georgina harem and that the revamp/rework/whatever they're calling it that's planned for the earlier chapters (and I believe this one too) will un-separate the Jennifer and Georgina paths. Or if that's not on the cards, allow either of those paths to be opened in Ch4 so we can get the D+E+J+G harem.
