With such bizarre life backgrounds and two so similar people, why do we always miss them inadvertently? Why don't you know he is behind you? Why do you always miss it? Why do you never look back?
He is a glittering rich man, he is a homeless black market boy, he is your mysterious deskmate, where should you go?
Behind the meaning of back, love often comes the moment you look back, the moment you turn around. It is at your fingertips, but it is fleeting. It depends on whether you look back and have the beauty of back.
