Friday, December 23rd. Two days before Christmas, the streets were full of people. It was time for Seonwoo, who had reached the crosswalk at the end of the downtown area against the crowds, to take a step while cooling off his tired head from repeated overtime. Closer, closer. The sound of a nightmare-like loud horn was heard as the noise and carol-soothing songs broke through his ears. If someone hadn’t pushed him away, it would have been the last sound. Without even having time to say thank you to the woman who saved him.
