Alright then whatever you say, but that is implausible and what do you mean by "guilt" what guilt are you talking about Bella having done some sort of thing to Jill? I never seen anything of sorts in the game of guilty except for what happened after when the MC kissed Bella. Bella told Jill to date the MC so that she can't cheat with the MC since she is "married". Bella feels guilty because she kissed a student and because she is a married woman.
What are you on about here?
Yes, Bella does feel guilty for kissing a student, that much is clear, but she also expresses guilt for having been intimate with a friend.
She doesn't consider the MC to be a friend, so it can't be him, it also doesn't feel like this is referring to Jade, Cathy, Stephen, or any other known character besides the one person who we know is her actual friend. The guilt she feels with the MC is likely reminding her of a past incident with similar feelings of betrayal, that's why she thinks this thought when thinking about the MC.
When she says that the friend incident was different, it could easily be because her intimacy with the MC is based on actual feelings for him whereas the possible incident with Bella was simply a moment of vulnerability on either or both of their parts that ultmately didn't mean anything more.
Yeah, we knew that at some point we would find out who is with Josy, but I doubt a lot of people thought it was going to be with Maya since back then people didn't except her to lie to the MC like that. But anyway back to the point, so what you are saying from what I observed on you is that if two girls are friends or best friends, they could be intimate, sure they could but that's very and I mean very unlikely.
Well I for one did think it would be revealed to be Josy. I wasn't around in this thread when that speculation on Josy's boyfriend was happening, but when I played it last week for the first time, it became very apparent to me around the time when the MC agrees to help Maya with her scavenger hunt challenges. There was something in that conversation, I can't remember exactly what, that made me literally shout, "It's Josy!". Then with the whole "march of the rejects" thing and Josy asking for the MCs room number, that sealed it for me.
As for girls who are friends being intimate, it does happen, whether it's a slobbery drunken kiss at a party, or as part of a drinking game, or a moment of weakness when they're feeling vulnerable and in need of intimacy. Hell, the "dildo spin" game has girls kissing girls. That's still intimacy, even if it's just a fun party game.
You see one thing I see one thing, but I think the more important thing is what DPC sees. Sure there is women that are bi and friends that kiss each other but don't have an actual real relationship, but not all of them, but what I've experienced with Jill and Bella and my shit ton of playthroughs that these theories that your posting doesn't fit the characters at all. We already have a lesbian couple as well I don't think DPC wants to have a story of Jill and Bella being or were a lesbian couple.
Again,
I AM NOT SAYING THAT JILL AND BELLA HAVE BEEN OR EVER WILL BE A LESBIAN COUPLE!! Two people can, and do, share an intimate kiss that doesn't lead to anything and that they can both move past. That's all that I think this is.
Everyone can post theories I get that, but these theories your posting doesn't make any sense to me, I have replayed this game so many times and looked around for clues and shit, these theories you posted about the harem route and Jill & Bella doesn't make any sense and it sounds like you want to make it a thing.
The harem thing I mentioned earlier wasn't a theory, per se, just more of a fantasy hope that I don't believe will happen. It's just that I like all the main girls and, at the moment, don't really want to see the MC break up with them, even though I know he likely will have to.
Jade and husband wanted to spice up their (failing) marriage. Husband proposed: "Hey, why don't we involve Bella?"
