One of the best dramatic scripts in an AVN, and with high production values too. The first game I've played where I go back to the non-sexual scenes again and again to relive them. It doesn't quite escape porn tropes, but wouldn't be a large edit to get to a story that would be plausible as a mainstream feature.
Regardless of your specific choices, the story is about a group of people (6-7 women and 2 men) who become great friends over an amazing summer. The plot is mostly driven by Lexi and Cece. Lexi is a great person and continuous good vibes; her exciting life and generosity provide much of the story's framework. CeCe is a wild ride that alternates between highs of sublime sweetness and emotional rock bottom, You will, at the very least, be very emotionally intimate platonic friends with Cece, and the beats of that relationship are likely to be what you remember about the game long afterward.
The other women have some subplots that provide genuine entertainment value. There is unrequited love and healthy dose of comic relief. They are likable enough that you will feel bad about not picking them romantically.
So who should you pick romantically? I would start with Cece, unless you really aren't into her at all. The surprises will hit harder with additional emotional layer of romantic love and deserve to have maximum effect on the first play through. But this game has high replay value: picking other women resolves other plot points, and unlocks other scenes, some sexual and some funny or heartwarming.
I purchased on Steam with the walkthrough add-on; it is well worth the money to turn this feature on in a second play-through, as you're unlikely to unlock all the awesomeness without some hints.
But here's a hint: some tasks just naturally complete in the narrative without you choosing anything, but others require you to check your phone and interact with the chat or social media ("Nuke") app. Look very subtle hints from the MC that he is bored or wishes there was a way to do something, and then poke around in those apps.
