a thought that occurred to me while playing the game is that the mc can be a bit of a mary sue. after some thinking, i don't think that's true - the mc is just the only decent person in a room full of people who are not used to that. and while i can see this being the whole point of a character - someone being so perfect they better the lives of people around them, - maybe that's not what you guys were going for?
i enjoy main characters having their own personalities, and this vn has had a good one so far. just inserting my two cents here, the mc fucking up would be neat, right now he seems way too calm and collected. the only flaw i saw in him was being too invasive with kota, and even at the end of chapter 18 his outburst of anger was justified. it doesn't have to be anything major though, small missteps just make him feel more human, i think
