Man, I love the vibe of this visual novel and I totally understand what's going on. I mean, I would also cheat and feel incredibly bad about it, but when I realized just how much was hinged on my grades I started to become numb towards it. I stopped cheating but the fact I got used to cheating all because I was afraid of failing never left me. Amazing visual novel, especially with the additional words you leave behind.
Becoming numb towards cheating at some point sounds quite... familiar, being more focused on grades than honesty, but students should never have to be afraid of failing.
We should be excited to learn and not care if we fail since failure is part of learning! But... You know.
