forgive me if im wrong, but some of the personality for M is decided on the quiz at the start, so idk if you chose more introverted options for that, but if not, i would recommend just choosing the most introverted options for the quiz at the start, and that may shape some more of the personality. I am very much an extrovert tho and pretty much chose the most extroverted options the whole way through, so, idk lol. but if im wrong then hopefully theres more introverted mc in the future.<3
