First I just had a hunch, as I know i've seen the disclaimer with that "press my button part" and the name Mushi sounds familiar... Than I took a look around on itch and found VNs (but nothing that I've played yet, if I remember correctly) and the presskit and I became certain that this first chapter lacks compared to the rest.
I'm not asking for perfect or exciting, believable and relatable would totally suffice for me. Give the reader just enough info on the world to make the characters actions and thoughts believable, mention some superstitions being or becoming true (or rumours of such a thing) for example... I just don't like to feel doubts in my escapism, I'd say.
I love to relate to characters (not always the protagonist as they are often blandly good or villainous, but there were really well written protagonists too), but at this point there is none to relate to, as the protagonist is more of an empty canvas at this point, we know about as little about her as we do about the 3 rapists, therefore her reasoning doesn't make any sense, even reading it several times doesn't help finding anything to relate with anyone so far. She's not really charming (and i'm not a fan of overly sized, borderline obscenely big, busts) hence I can't relate to the rapists. Apart from her having a name there is nothing to relate over to our protagonist either.
Don't get me wrong I don't mind a more shallow story from time to time, but these live from fleshed out characters (at least one to love or hate), while you can get away with rather shallow characters, if the story itself binds the reader.
But Lolas story just starts with that strange conclusion after getting raped, a conclusion that could be anything from her being really stupid, over a coping mechanism, to magic, charms and curses are just a normalcy in that world and you need to go on an adventure to solve the problem. If I hadn't seen your other stuff on itch, I don't think I'd give the VN the benefit of the doubt at this point, quite likely I'd not even taken the time to write a review.
