I really hope that's the case, it seems ORS is more strict about relationships compared to GGGB.
Ashley could freely mess around when in an open relationship and even when not, she can even keep cheating till the end after she gets married. Still it seems weird to me that Ian cuts off Alisson and Emma but has no problem sleeping with Cindy, hell Lena can even cheat on Ian with Mike when he's right there with her in the club...
So why did Eva draw a red line for cheating on Lena with Alisson or Emma specifically ??
I think it is more likely that Cindy is the exception rather than Alison and Emma.
The game already did stuff to setup Cindy and Lena as rivals, and the eventual outcome of IanxCindy will already involve some burned bridges either way
if it were to ever come to light, so I think the story doesn't change much from Lena being personally wounded by it.
Emma on the other hand is chill with everyone, and she is the one who stops pursuing Ian once she learns he and Lena are in a serious relationship now. I would be straight up shocked if she isn't an eventual candidate for threesomes and open relationship stuff
later but for now you'll miss some exclusive scenes with her.
Alison is a bit more interesting, I don't really know why the dev wants her to not be a direct source of conflict with Lena like Cindy will be. My guess is that because Ian cheating on Lena with Alison wouldn't really
fracture Ian's friend group like the revelation of the Cindy relationship will, but also because Alison doesn't have the same stakes as Cindy to also want to keep their relationship hidden for as long as possible. I do think it would make sense to eventually be able to get some threesome stuff with Alison if you
didn't get her hopes up and mostly left her for Jeremy since she would still have a crush on Ian and Jeremy does a lot to "corrupt" her, but I guess the dev is not interested in Alison having too much impact on the main story so same as Emma stuff with her is on hold until Ian and Lena can talk more about how they want to "experiment".
