Nostalgia and Lust is a game about sitting in front of a computer.
I kid, but I kinda don't. The vast majority of the game consists of scheduling your childhood friend's streaming career and managing her money, which is all done in front of the computer. You can choose what games she plays, which additions you want to make to improve her videos and keep track of her fan base. Unfortunately, this is all without art as of yet and the numbers seem to have enough variance to them to where it's difficult to tell if you're even making the slightest amount of difference. Mostly, it's really tedious and unrewarding.
When you finally leave your computer (once or twice a week), there's NTR content (and maybe dating?) to find. Basically, if you get enough money to pay the childhood friend's rent you can pay it to avoid NTR. You can also knock on her door to see if she wants to spend time with you, which appears some level of random. I played two weeks before I gave up.
Frankly, the gameplay is the problem. When "managing" the childhood friend's streaming career consists of no images, little feedback as to what improves income (or a tutorial), and no opportunities for corruption, I'm left wondering why I bother. When a game touts itself as a "youtuber simulator" I expect that to be at the forefront. Currently, the game feels like a scene gallery with filler getting in the way.
There might be good NTR scenes, there might be a lovey dovey childhood friend romance, but I'm not about hitting skip day or navigating a system with no guidance to try and find them. I like the way this game looks, but if it wants to be an actual game, it needs to have some sort of a rewarding or entertaining gameplay loop before anything else. Otherwise, it'd make a better scene gallery.
