What story? There is significantly more gameplay and puzzles currently then story content. It's not like we even have the whole story yet anyways. The only story we currently have is Find Kari, Find Yuri, Talk to Kari and Yuri about Nanami, Go to mall with Kari, Meet Yuri at Mall, Meet Nanami at her job, The Sleepover, and Yuri's Nightmare. The journal is blank after that. We know next to nothing about Nanami before or after the sleepover. I don't even think that the player can even interact with her at all since the player can't talk to her at her job and I can't find her at all in the school. Kari basically just wants to turn you into a woman. Yuri wants to help you turn back and actually has an interactive follow up scene but the player has to go out of their way to trigger it. Rin disappears after your encounter at the Outpost saying you shouldn't be there yet. The characters we know the least about are Rin and Nanami and we don't have any ways to interact with them. Rin is one of the hardest characters to try to interact with since you have one time encounters that have massive green bar requirements to unlock dialogue options. If you don't know about them ahead of time, which why would you given that this game is supposed to be difficult, then you need to load an earlier save or start a new one just to further interact with them.
