Do you know what a murderer looks like?
It's me.
It is unremarkable and the most inconspicuous among the crowd.
Others say I have a gentle personality and a good temper.
But one second I was smiling at you, and the next second my knife would cut through your artery.
Life treats me badly, why can't I retaliate with evil?
I will not let go of those who have ruined my family.
Old people, children, no one is innocent.
I want that person to watch his family die tragically and be unable to do anything.
Determination: If life treats me badly, I will treat it badly in return.
