I wish the dev didn't make the MC's sister so hot if he wasn't going to do incest.
I don't even really think that's the root of the problem. What didn't help is that she's basically introduced with the same up/down "checking her out" pan all the love interests get, the first time you talk to her in person you get the lingerie shot, and then there's the nude scene in the bath tub.
Pretty much
everything in the game as presented makes it seem like she's going to be an eventual incest LI option (possibly as part of a threesome down Jane's route, because there's subtext there if you're looking for it). She comes across like one big cocktease on the part of the dev. Maybe even as deliberate mocking of all the people asking for her to be a LI, or just out of distaste for the idea of incest in games in general.
So yeah, it makes sense that people who are into the idea or who find her attractive keep expecting the next update to be the one where something happens. Or hoping it is. Or just asking whether or not it is. Sure, the dev may have said it's never going to happen, and people can easily repeat that every time it comes up (and I'd even agree that it
shouldn't happen, because the story works better without it), but most of the actual in-game presentation makes it seem like she definitely should be. She's pretty much Chekov's Incest Gun.
Though honestly, I'm just sad we couldn't do something with Rachel.
Emma was my favourite, wish she got a better ending
Well, you could always head-canon it for yourself that after she goes to school and betters herself as a person, while you pursue a successful music career, you still stay in touch via e-mail and texts and phone calls, and eventually hook up again down the road, now in a much healthier relationship because you're both much more mature, self-actualized people.
Sort of a "if you love something, let it go" sort of scenario. Your love winds up being made stronger by virtue of being apart.
Could probably be an even more likely outcome if you've avoided showing interest in any of the four main girls, or had them dump you for trying to play the field. A route where you mostly just stick to casual flings or even one where you mainly stay celibate and focus on your music career could feel more like you're saving yourself for her, because deep down you still feel like she's your one true love/soulmate.
And I mean, that kind of emotional longing? It'd probably make for at
least a few songs worth of soulful lyrics. Next album's gonna be double platinum!
