Hi! Thank you for the questions and for supporting the game.
If you choose the Open-Harem route, the three girls will later have the option to develop relationships with each other (and the protagonist), effectively becoming a polycule of four. You can also choose to just keep Valerie's interactions with them sexual-only if you prefer.
I'll consider adding two different paths for Valerie's corruption: moral or sexual, with either one opening the doors for (optional) physical succubus traits.
Thanks for the reply!
LOL yeah I actually went back ad checked out the Steam changes afterward and got to the section where you pick the three relationship options.
The two different paths would be great! I don't view being sexually active as corrupting (Which can make some otherwise fun VNs annoying where anything outside a traditional monogamous relationship is portrayed as corruption) especially since sex is a natural part of who and what she is, plus I am enjoying having my characters be heroes but I also want the succubus character to look like a succubus.
