While I agree that a year's time would feel more realistic, especially that plotting against a tyrant may reasonably take as long, the story would either have to be significantly diluted to match the longer timespan or take twelve times as long to write as it does now. One thing I love about this game is that it's actually going to be finished, unlike numerous visual novels out there. I play Vexx's route, with whom the MC has a long backstory, so all they have to do in this one month is pick up where they left off and confess all their previously unspoken feelings, which makes the whole thing more believable.
