Having read through this thread after checking the story out, I find a lot of people's concerns to be exaggerated at best.
Maybe it's just me, but most of the relationships were well implied with the only one being a head-scratcher being Katherine, who I thought might be an Aunt (clearly too old to be another sister, not much marital affection shown so far to sell the step-mom role). Cassie was clearly a sister, though the revelation of her being a twin specifically in this thread was nice. Ashley was
very clearly a little sister. Andrea was very clearly a mother.
The other big concern I understand, but which is somewhat overblown is the "passiveness" of the MC. If you think it through, his outward acceptance of the situation is logical and smart: These are women who can alter his mind, and who have confessed to doing so in the past. The honesty, while not "fixing" it, should at least buy them time to explain. They could easily have lied and claimed to never have done so to save face (though that would logically lead to a shit-storm when MC inevitably found out on his own). However, a monologue to show him as not so accepting inwardly as he appears outwardly would not be a bad addition. I will concede though that the towel incident was kinda silly. To paraphrase someone earlier in the thread "bruh you already showed them your dick just walk over there and grab the damn towel!"
Someone also commented on the foreshadowing with a few things in particular, and yes some of it is a bit on-the-nose, but I'm more than willing to see how it goes. Who knows, the dev might even subvert our expectations in a
good way!
Naturally, this is all just one user's experience and thoughts so yours may be different (as clearly many have been). That being said I look forward to the development of this title. With a bit of polish (some grammar issues, maybe some monologue to make MC's mindset clear, etc.), the stable foundation presented here can become something quite nice indeed.
