guys do you have a guide or tell me what do we have to do to unlock scenes ? i'm just exploring the city
For the first chapter of the game, you just need to do supply runs in the city to build up stats. You need to get your Likability with Yukino up, as well as the stat you get for contributing to the Community by selling stuff to that one lady. It may or may not also require owning a certain number each resource as well.
For an idea on likability with Yukino, the only two scenes with her I got in the first chapter was holding her hand when she stands near the couch, and hugging her from behind at the workbench.
After you're out of Chapter 1 you are free to pursue scenes freely. The quest log in the menu lists them all out already. I'm using textractor to play the game, but you can also just use the snipping tool and google image translate if you don't have something else to mtl the text.
