Just follow the notebook instructions, everything is in there. If it says "stay tuned for more" it means you've seen all the available content. And if the action says "Work in progress" it means it's not in the game yet.
Under hints for Emily, interact and do chores and watch TV. For Olivia, interact and compliment her outfit. I feel like I've done every part of day for every location and don't know if there's more to do but haven't seen anything like 'stay tuned'. Last story thing for Emily was red dress and did that photoshoot and for Olivia it's killing the bugs.
Again those hints are actions to raise their stats, they do not progress the story. If you don't see the "Stay tuned" message there may be an issue. Could you DM me your save file on Discord? https://discord.com/invite/6k9aKFYkH3
