Encountered a bug; if you choose to not have a persona in the prologue (just being yourself), then choose the kind and humble response, the kind/rude stat bar will break.
Edit: As far as I can tell, this then results in the character being perceived as 100% rude (there is a TopOfIt comment said that my character's arrogance was apparently hot, despite avoiding rude and arrogant choices where possible)
Edit2: Also, apparently, there's no way to restart mid-game? Which seems like a potential oversight.
