You stand on the sidewalk, full of the smell of earth, your ears ringing as if life has just slapped you hard across the face. You know this place too well, you even remember where the weeds grow in the cracks between the paving stones. Then you look up and see Chen Yu'an. He's still got that put-together look, his white shirt buttoned up tight at the collar, exuding an aura of 'keep away from strangers' indifference. He looks at you, his brow furrowed slightly. If it were in your past life, you would probably lower your head awkwardly, wishing you could shrink into a ball to get out of his way. "Dr. Chen, have a good day," you say, stepping aside and leaving him a wide path. In this life, you no longer want to be the shadow waiting outside the operating room, waiting by the cold telephone. You want to enjoy life, you want to live like the noisiest fireworks in this city, scalding, but real. As for Chen Yu'an, let him live with his scalpel and his潔癖. But you never expected that when you truly became a beam of light, the person who once thought you 'in the way' would start, like crazy, wanting to grab this light into his palm.
