K-pop AU meme: Shin Dongho - “2 realities”

He is going to the place of another mission; he is going to kill another man.
He arrives and someone makes a sign, showing him where the victim is this time.
He walks through the lights of the street and takes his gun, ready to make the ground red like blood.
“You ready?” he likes to tease the victims. He likes to see the pain in their eyes.
But when the man looks back, it happens to be his best friend, Kevin.
“I didn’t know you had this kind of life. I think I’ve never really known you. Come on, hit my chest.”
His heart aches hearing those words. For the first time he feels like a human being.
