tl;dr unlock the gallery and watch the scenes there
you can more or less divide the girls in 2 categories: the prudes and the throwaway bitches.
the prudes are easy to recognize, nothing will ever happen with them and they all follow the same template:
-an event of some sort happens
-the girl feels either sad or lonely
-mc says "let's do [x] to cheer you up"
-girl says 50 different shades of "golly gosh mc you're the best"
-mc says "gosh golly [insert girl name/relationship here] you're the best"
-they hug and kiss in any spot that doesn't have lips.
-scene ends.
literally all of them follow this template and there's no real indication of progress with them, since they each have multiples of this type of scene, and all of them end the same way, with nothing ever really happening.
the throwaway bitches are also pretty easy to recognize. they get introduced and either 2 seconds later or the second time they meet with mc they have sex.
also, whenever mc speaks with these girls the only words that come out are a series of badly strung-up pickup lines that i can't imagine any actual human saying out loud unironically
they barely get any screen time and were probably introduced back then because people were getting fed up with the constant stalling, so that the dev could just say "uH tEcHnIcAlLy ThErEs SeX sCeNeS
" without actually giving the well liked characters anything and keep people wanting.
either that or just to write up "there's [x] new sex scenes" in his report, to try and stop people from leaving
why do i think that? well, because all of them are abrupt and out of nowhere, whether the scene is there or not doesn't really change anything, and there's no actual logical reason for those characters to do it, other than magically feeling the need to spread their legs to mc for some divine reason lol.
there's nothing really sexy or exciting about them either so they're kinda whatever anyways.
you can expect sex scenes with the prudes after the college girlfriend comes find you, which is waaaaay later.
the dialogue writing is pretty cringey, felt like i was reading one of those romance books whose target audience is adolscent high school girls or something
in other words, this game is just a series of events that are only meant to leave whoever is watching in a state of wanting (gotta bait those gullible idiots to throw money somehow right?
), the characters will just say a bunch of slightly suggestive shit, the dev will give them tight fitting clothing, and voilà, scene done.
if you watch the gallery replay you'll still be able to figure out what's happening anyway, so i'd recommend doing that if you really want to see what's happening in this game without wasting time lol.
this game is for sure not worth the amount of time i personally spent on it, which was almost a full day
