Great another goody goody MC, he saved her life but instead of expecting any kind of repayment even though she's obviously omega rich like many copy paste heroines, he's thinking about how to give her benefits that she doesn't deserve, just **** off.
Followed by MC being completely convinced after one single fight that he's OP and will steamroll over any monster the school might throw at him, now I'm not saying he's wrong... But he apparently cannot even remember shit so how can he be so sure.
And the randomly super developed chest girl that's also bullied in school by everyone so MC can become the sole support is just disgusting for a plot convenience.
