I don't know how far I am into this game, but our MC gives me major whiplash. He has all of these women fawning over him, but has the emotional intelligence of a block of wood. But then knows exactly what they are thinking... unless they are obviously distressed, in which case he's back to being braindead. The author tries to have him come across as smart sometimes, but then just has him be an idiot when having a clue would be useful... perhaps in an effort to make the MC look tough for saying no to people? But it comes across as naive. He wants to know all about his grandfather, but when presented with people who could possibly give him actual answers, he's rude and arrogant. But more importantly slows down the over-arching story being told. There's the idea in role playing games that it is assumed that everyone playing wants to play, and therefore will agree to pursue the quest the DM presents them. Our MC wants answers... and then refuses to even attempt to get the answers once people don't just say "ok, I'll tell you everything." He doesn't have to agree with whatever someone wants, but not just shutting the proverbial door on them would go a long way to keeping the plot moving.
And I'm sure I missed it as a passing line in the beginning, but why is he going to school if he plans to fail? He does realize that there's no benefit to attending school if you're both going to fail and sleep through class, right?
Anywho, minor rant. The game is good, but there are multiple conversations that sound like the MC is trying to push the plot to a different update as opposed to just getting the answers he claimed to want thirty seconds ago.
