It's non-linear! Basically the events/plots trigger based on the characters' feelings for you/how you interact with them, so it can get a little random at times! Once you pick up a plotline it'll unfold as you go along, so hopefully it feels a little more organic. There's an unlock guide here too with info on how to trigger most of the main characters' unlocks: https://suiteddevil.itch.io/slasheru-act1alpha/devlog/536712/walkthroughhints-ac...
