whatever's out rn within the game is only a demo so the structure of the storyline is only a section of what it is as a whole in comparison to when the full game releases meaning whatevers happening between the characters (mc and qui/tamarack) is only a glimpse into what it plays out to be, it is only a demo not the full game thats why information and filler is missing. In the game there are ONLY TWO characters you can choose the romance route with as of now meaning the characters you are referencing (qui's group of friends) are not characters you can interact with in the sense of making them romance options. This is technically a romance game but can be played through with the platonic storyline with the two characters but if you are not interested in 1. qui (male - non binary) or 2. tamarack (female) in the romantic sense or the platonic friendship playout then i genuinely dont think this is the game for you as of now and would recommend you dont complain about the character options as the game is not targeted towards you and has a different audience, especially since there are many limited female and male tropes within games.
