On the sharing submissive path, I think Emilie shouldn't have admitted she was faking it with Ethan if MC doesn't kiss her, it kinda makes the whole scene with Ethan pointless, she should continue trying to make MC jealous until the player gives in, as that was the whole point of it, immediately saying she faked it would negate the faking.
My main playthrough will always be the love routes for every character, I only went through sub and sharing routes to fill up the gallery, but it would still be better if they made sense and not wimp out on trying to make MC jealous, just to name an example, if you're going to spend time making those routes, at least do it properly, she was so determined to make him jealous, so she shouldn't give that up right after the sex scene ends, she should follow through with it.
I really hope there will be a full gallery unlocker someday, I'm missing the second to last scenes on both the love and submissive paths for Emilie, and I don't know how to get them at all.
