Soo Yun is a 23 years old girl who had spent two months in Seoul because of her job. Tired of being isolated from her family and friends, she decides to go back to her city. She was just enjoying her ride home when everything went to hell. Trapped on the train, she has to fight for her life with others survivors until the last stop: Busan. This story is based on "Train to Busan", so is basically a fanfiction. Almost everything that is on here it's not mine, even though I'll change some things in the storyline. Soo Yun belongs to me.
