I find it interesting that Edward chose to ask Alice about his situation with Emma, I think that the most likely path for future sex scenes is going to be Emma, and other girls perhaps, but if you're holding out for Elsa or Alice scenes it's probably going to take longer. Like I wonder when Ed decides to give that black haired girl from the pub a call, seems like an easy excuse for a quick sex scene by the dev, without needing to create whole new character arcs to justify it.
All in all, this game is great, I'm not bothered by the slow burn, let the developer take his time, I just want it to be coherent.
