The game is a sandbox, so there are no “clear routes” that you can follow to get 100% of the scenes. Replay scenes and if something new doesn't appear, then this branch is over (or will be continued in future updates). You can ask in the Discord channel specific questions about the walkthrough.
I'm not asking for a clear route or linear path. I've played many sandbox VNs (HHG, Goddesses Whim, Mythic Manor, Scarlet Law, School of Love, AI Revolution, etc.), and pretty much all of them provide the player with a way of checking if all content is complete for the main story and/or a girl. This way I can choose what events I want to do in any order, hence the sandbox aspect.
Here, there's not even a way to check the trust stat for any of the girls, or how much trust you'd need for the next event. Just something that shows progress would be helpful.
