Kroger brand Miyu brings up an interesting point about helping others at their lowest. As manipulative as it is, she actively improved the bully's life versus the MC's passive kindness. Is he actually kind if he doesn't take time to check up on people he supposedly wants to help? He just lets people walk all over him and comes to resent them, as seen by his reluctance to accept his bully's apology and backing out from listening to the cheater's worries. It's realistic, but damn if it makes him such a massive hypocrite.
