Idealistic idealists, even if they are persistent and tenacious, are still weak. They do not understand that in this world, there are many things you can't understand but must accept. Only those who truly understand the ugliness and filth of this world, who are struck by reality, tortured by pain, bear the scars, and have nowhere to hide, yet never give up the pursuit of light and continue to smile and move forward, are the true heroes. Those who have not experienced darkness cannot understand the light.
